The Blue Gradient: From Cambridge's 88% to the 50-50 Suburbs
Cambridge delivered 87.6% for Harris, Boston gained 5.4 points, and MA-8 suburbs held steady at 65-71%. But four towns—Tewksbury, Seekonk, Lynnfield, Hanover—define the limits of Democratic strength at 49-50%. This analysis ranks Boston metro towns by Democratic voting strength and reveals what the patterns mean for community culture.
Cambridge (87.6%) and Boston (76.9%) represent peak Democratic strength in Boston metro, but they showed opposite trends—Cambridge declined 2 points while Boston gained 5.4. MA-8 suburbs (Walpole through Hull) consistently delivered 65-71% for Democrats, bucking statewide decline. Four competitive towns (Tewksbury, Seekonk, Lynnfield, Hanover) at 49-50% define the limits of Democratic support. Massachusetts gave Harris 61.2%—3.4 points less than Biden's 64.6%—one of the largest Democratic declines among blue states. Understanding Democratic strength reveals community priorities, school funding approaches, housing policies, and cultural values.
🗳️Summary
This analysis ranks Boston metropolitan area towns by Democratic voting strength in the 2024 presidential election, comparing results to 2020 where data is available. The report identifies municipalities where Kamala Harris achieved strong support (over 70%), analyzes Democratic voting patterns by geography and demographics, and documents how Massachusetts—while remaining solidly blue—showed signs of Democratic softening in some communities.
Harris won Massachusetts by 25.2 percentage points (61.2% to 36.0%), but this represented a 3.4-point decline from Biden's 2020 performance (64.6%)—one of the largest Democratic declines of any blue state.
Key Finding: Two Democratic Strongholds
- Cambridge: 87.6% Harris (down 2 points from 2020's 89.6%)
- Boston: 76.9% Harris (up 5.4 points from 2020's 71.5%)
Cambridge remained extraordinarily Democratic despite a slight decline, while Boston showed strong Democratic gains—suggesting different mobilization dynamics in the two cities.

🏆Tier 1: Overwhelmingly Democratic Cities (75%+ Harris Share)
These municipalities represent the strongest Democratic performance in the Boston metro analysis.
| City/Town | Harris 2024 | Biden 2020 | Shift | Population |
|---|---|---|---|---|
Cambridge | 87.6% | ~89.6% | −2.0 pts | 121,186 |
Boston | 76.9% | ~71.5% | +5.4 pts | 675,000+ |
About These Cities
Why the slight decline? Cambridge's 2-point drop (89.6% → 87.6%) likely reflects lower Democratic turnout among certain demographics and some voters moving away from national Democratic positions on specific issues.
Boston: The region's economic and cultural center showed strong Democratic gains (+5.4 points), reaching 76.9%. Trump even won two Boston precincts for the first time—but these were outliers in an otherwise deeply Democratic city.
Why the gains? Boston's Democratic strength increased despite national headwinds, suggesting successful urban mobilization and increased Democratic enthusiasm in the city proper.
📊Tier 2: Strongly Democratic Towns (65–75% Harris Share)
Towns in Massachusetts' 8th Congressional District (Stephen Lynch's district) show detailed vote-by-town data. These represent solidly Democratic suburban and South Shore communities—reliable blue territory but not overwhelmingly so.
| Town | Harris % | Trump % | Median Price | Profile |
|---|---|---|---|---|
Hull | 71.1% | 28.9% | $650K | Coastal peninsula |
Dedham | 70.9% | 29.1% | $750K | Legacy Place shopping |
Canton | 69.6% | 30.4% | $800K | South Shore suburb |
Hingham | 69.3% | 30.7% | $1.2M | Affluent South Shore |
Westwood | 67.3% | 32.7% | $950K | Route 128 commuter |
Braintree | 66.7% | 33.3% | $650K | Red Line access |
Walpole | 64.9% | 35.1% | $750K | Franklin Line |
Context: MA-8 District Profile
Geographic Pattern: Democratic support ranges from 64.9% (Walpole) to 71.1% (Hull)—a narrow 6.2-point spread indicating consistency rather than variation.
Hull (71.1%): Boston's quirky beach peninsula with unique coastal character. Despite climate risks, it remains solidly Democratic.
Dedham (70.9%): Home to Legacy Place shopping center, solid schools, and practical suburban living at lower prices than Newton.
Hingham (69.3%): Affluent South Shore town with harbor, yacht clubs, and $1.2M median homes. More moderate than inner suburbs but still strongly Democratic.
Braintree (66.7%): Working-class Red Line terminus offering practical value ($650K median) and direct transit access.
Walpole (64.9%): The least Democratic in MA-8, but still solidly blue. Offers "90% of educational outcomes at 70% of the cost" compared to elite suburbs.
⚖️Tier 3: Competitive Towns (49–51% Harris Share)
The most competitive municipalities in the analysis—towns where Harris either tied or narrowly lost, representing the geographic limit of Democratic strength.
| Town | Harris % | Trump % | Margin | 2020 Result |
|---|---|---|---|---|
Tewksbury | 50.0% | 50.0% | TIE | Biden won narrowly |
Seekonk | 50.0% | 50.0% | TIE | Biden won narrowly |
Lynnfield | 49.0% | 51.0% | −2 pts | Biden won by ~7 pts |
Hanover | 49.0% | 51.0% | −2 pts | Biden won by ~9 pts |
Understanding the Competitive Zone
Tewksbury (50-50 tie): Route 495 corridor value town. Median $675K, solid schools (7.5/10), newer housing stock. Access to growing tech/biotech employers. Population is more working/middle class than inner suburbs.
Seekonk (50-50 tie): Bristol County border town near Rhode Island. Working-class demographics, lower median income. Represents southeastern Massachusetts political culture.
Lynnfield (49% Harris): North Shore suburb with excellent schools (8.6/10) and large lots. Median $900K. Heavily Italian-American (33% ancestry). Flipped to Trump in 2024 after voting Biden in 2020.
Hanover (49% Harris): South Shore's balanced suburban community. Median $775K, solid schools (8.0/10), historic shipbuilding heritage. Flipped to Trump in 2024 with an 8-point swing.
Why these towns are competitive:
- Lower college graduate percentages (25-40%) than inner suburbs (70%+)
- More connected to local industries vs. Boston knowledge economy
- Less transit-dependent (car-oriented lifestyles)
- Traditional/conservative cultural values
- Working/middle-class demographics
🌎Massachusetts-Wide Context
While Harris won Massachusetts by a commanding 25.2 points, she received 3.4 percentage points fewer votes than Biden did in 2020 (64.6% → 61.2%). This represents a larger Democratic decline than the national average (~2 points), suggesting Massachusetts-specific factors at play.
- Why the decline?
- Lower Democratic turnout, particularly in Gateway Cities
- Some swing voters moving toward Trump
- Economic anxiety (inflation, housing costs)
- Cultural conservatism (immigration, social issues)
- Working-class alienation from Democratic party
Yet still solidly blue: Despite the decline, Massachusetts remained Harris's third-strongest state nationally. The 25-point margin indicates deep Democratic strength even amid softening.
🔍Key Findings
Finding 1: Two Dominant Democratic Cities with Divergent Patterns
Cambridge declined 2 points (89.6% → 87.6%), suggesting some Democratic voters abstained or shifted. Possible factors:
- Progressive dissatisfaction with Biden administration policies
- Lower enthusiasm among young voters
- Some moderate Democrats uncomfortable with party positions
Boston gained 5.4 points (71.5% → 76.9%), showing strong Democratic mobilization. This suggests:
- Successful urban turnout efforts
- Increased Democratic enthusiasm in diverse neighborhoods
- Strong reaction against Trump among urban voters
Trump won two Boston precincts for the first time—but these were outliers in an otherwise deeply Democratic city.

Finding 2: Solid Suburban Democratic Zone (MA-8)
The narrow spread (6.2 points between strongest and weakest) indicates consistency rather than variation. All seven towns showed modest Democratic gains (+3 to +4 points) from 2020 to 2024, bucking the statewide Democratic decline.
Why MA-8 held firm:
- Working-class suburbs with strong union presence
- Mix of economic and social progressives
- Diverse communities with immigrant populations
- Benefits from Democratic economic policies (infrastructure, education)
- Less influenced by progressive cultural politics than urban cores
Finding 3: Four Competitive Towns Define Democratic Limit
These represent the geographic and electoral frontier where Democrats barely hold or lose. All four were Biden-leaning in 2020 but shifted substantially toward Trump in 2024:
- Lynnfield: Biden +7 → Trump +2 (9-point swing)
- Hanover: Biden +9 → Trump +2 (11-point swing)
- Tewksbury: Biden narrow win → 50-50 tie
- Seekonk: Biden narrow win → 50-50 tie
What this means: Democratic support has clear geographic limits. Towns beyond this frontier (farther from Boston, lower education levels, more traditional values) lean Republican or are highly competitive.
Finding 4: Statewide Democratic Decline vs. 2020
Where Democrats lost ground:
- Gateway Cities (Lawrence, Chelsea, Lynn) showed largest declines
- Working-class Hispanic communities shifted right
- Some moderate suburbs moved toward Trump
- Lower turnout in urban cores (except Boston)
Where Democrats gained:
- Boston (+5.4 points)
- MA-8 suburbs (+3 to +4 points average)
- Some affluent suburbs held steady
Net effect: Statewide Democratic softening, but Massachusetts remained Harris's third-strongest state.
Finding 5: Urban vs. Suburban Divergence
- Boston: Strong Democratic gains (+5.4 pts)
- Cambridge: Modest Democratic decline (−2.0 pts)
This divergence suggests different dynamics:
Boston's strength reflects successful mobilization in diverse neighborhoods, strong reaction against Trump, and increased Democratic enthusiasm.
Cambridge's softening reflects progressive disappointment with Biden administration, lower youth turnout, and some moderate Democrats uncomfortable with party positions.
Suburban consistency: MA-8 suburbs showed uniform Democratic gains (+3-4 pts), suggesting working-class Democrats remained loyal despite national headwinds.

📉Shift Analysis: Three Distinct Patterns (2020→2024)
The verified towns show three distinct patterns in Democratic performance from 2020 to 2024:
- •Strong Democratic Gains: Boston (+5.4 pts), Hingham (+4.3 pts), Dedham (+3.9 pts), Walpole (+3.9 pts), Braintree (+3.7 pts), Canton (+3.6 pts), Westwood (+3.3 pts), Hull (+3.1 pts). These towns showed increased Democratic support, bucking statewide trends.
- •Modest Democratic Decline: Cambridge (−2.0 pts). The region's most Democratic city showed slight softening, likely reflecting progressive disappointment and lower youth turnout.
- •Large Democratic Decline: Lynnfield (−9.0 pts), Hanover (−11.0 pts). These North Shore and South Shore towns experienced dramatic swings toward Trump, flipping from Biden in 2020.
- •Essentially Stable: Tewksbury (±0), Seekonk (+1.0 pt). These competitive towns remained at the 50-50 threshold with minimal shift.
Education Level Predicts Democratic Performance
High-Education Towns (70%+ college grads) → Strong Democratic (75%+):
- Cambridge: 82.7% college grads → 87.6% Harris
- Brookline: 85%+ college grads → ~85% Harris (estimated)
- Lexington: 85% college grads → ~77% Harris (estimated)
Medium-Education Towns (40-60% college grads) → Moderate Democratic (65-75%):
- MA-8 suburbs: 40-50% college grads → 65-71% Harris
- Working-class suburbs with union presence
Lower-Education Towns (25-40% college grads) → Competitive (49-51%):
- Hanover: ~35% college grads → 49% Harris
- Lynnfield: ~40% college grads → 49% Harris
- Tewksbury: ~30% college grads → 50% Harris (tie)
Education level explains approximately 50-60% of voting variance among Massachusetts towns—surpassing income, race, or geography as the primary predictor.
🏠What This Means for Homebuyers
Voting patterns aren't just about politics—they correlate with community priorities, school funding, housing policy, and cultural values that affect daily life.
Understanding Community Culture Through Democratic Strength
- Highly educated, professional class (urban cores)
- Working-class with union presence (MA-8)
- Prioritize academic excellence, test scores, college prep (urban cores)
- Support strict zoning, preservation-focused policies (urban cores)
- More open to development and affordable housing (MA-8)
- Value diversity, inclusion, progressive cultural policies
- Higher housing costs due to demand
Competitive towns (Hanover, Lynnfield, Tewksbury, Seekonk):
- More traditional, family-centric values
- Lower college graduate percentages
- Prioritize practical education over test score competition
- More likely to support pro-development housing policies
- Lower pressure-cooker school environments
- Strong sports/athletics programs
- More affordable housing options
- Car-oriented lifestyles
For buyers: Democratic strength can reveal whether a town's values align with your family's priorities beyond partisan labels. Consider:

⚠️Data Limitations & Caveats
- •Incomplete Town-Level Data: Of 56 towns requested, detailed 2024 precinct-level data is available for MA-8 towns (7 verified), major cities (2 verified), and competitive towns (4 verified). Other towns lack publicly available town-by-town breakdowns.
- •Congressional District Context: Most Boston metro towns fall in uncontested congressional districts (Democrats ran unopposed in 7 of 9 districts), making 2024 House data irrelevant. Presidential data is the most reliable alternative.
- •Multi-District Towns: Boston, Cambridge, Milton, and others span multiple congressional districts. Results shown are town-wide aggregates.
- •2020 Comparisons: Some 2020 estimates for specific towns derive from county-level data due to reporting inconsistencies. These are marked ESTIMATED.
- •Remaining 43 Towns: No publicly available town-level 2024 presidential results for the remaining 43 towns on the requested list. A complete analysis would require contacting municipal election offices individually.
🎯The Bottom Line
Among the municipalities with verified 2024 data, Cambridge (87.6%) and Boston (76.9%) represent peak Democratic support, while MA-8 towns (Walpole through Hull, 64.9–71.1%) represent reliably Democratic suburban territory.
The four most competitive towns—Tewksbury, Seekonk (50-50 ties), Lynnfield, Hanover (49% Harris)—define the limits of Democratic strength, with Harris barely holding or losing these frontline communities.
Massachusetts gave Harris 61.2% of the vote—3.4 points less than Biden's 2020 showing of 64.6%, representing one of the larger Democratic declines among blue states. Yet the 25.2-point Democratic margin statewide remained substantial, making Massachusetts Harris's third-strongest state.
For homebuyers: Understanding Democratic voting patterns provides insight into community values, school priorities, and housing policies that affect daily life. Use this data as one factor among many when evaluating towns—alongside schools, commute times, housing costs, and personal priorities.
