Blue-collar cities made the difference between Scott Brown upsetting Martha Coakley in 2010, and Elizabeth Warren toppling Brown two years later. If that pattern holds true, Sen.-elect Ed Markey could be sweating out his reelection effort next year.

A post on Blue Mass Group yesterday compared Markey’s strongholds to Warren’s, and found that Warren performed far better with blue-collar voters, while Markey’s strength was with the suburban chablis and brie crowd. Markey outperformed Warren in wealthy close-in suburbs like Lexington, Concord, Wellesley and Brookline. However, he fell far off the pace Warren set in cities like Springfield, Holyoke, Lawrence, and Fitchburg.

The Markey-Warren comparison puts a new spin on the relative softness of Markey’s 10-point victory over Gabriel Gomez. Last week, CommonWealth mapped the sharp dropoff in Democratic votes from the 2010 Brown-Coakley matchup. The Markey-Gomez contest drew nearly 1.1 million fewer voters than the 2010 Senate special election did. So even though Markey’s vote margins were far healthier than Coakley’s — he won by 10 points, while she lost by 5 — Markey only collected 60 percent of the votes Coakley did. That sharp dropoff in Democratic voting wasn’t uniform.

Statewide turnout in the Markey-Gomez Senate special election dropped by roughly half from 2010, but Markey’s wider margins in tony suburbs like Lincoln and Concord meant that the drop in Democratic votes was less severe in those towns. By contrast, Markey struggled mightily to turn out votes in cities like Pittsfield, and along the South Coast.

The lesson from Brown’s victory over Coakley was that Democrats can’t just count on turnout in Boston, Cambridge, and the wealthy western suburbs to carry them to victory. Warren poured huge amounts of energy into driving up turnout in blue-collar municipalities, particularly in cities like Worcester, Brockton, Lowell, Fall River and New Bedford, where Brown had eroded or even reversed Democrats’ traditional advantage. Markey fell far off Warren’s pace in these cities, and his vote totals compared to Coakley’s suffered disproportionately. These weaknesses didn’t matter this time around, against a surprisingly weak first-time candidate like Gomez. He’ll surely have to do better when the GOP gets a redo in just 17 months.
