This turns the MA election upside down: MA was not a victory for GOP, not at all. In fact, it was the exact opposite.
It was a defeat for conservatives, and a triumph for liberals: the Public-Option Rebellion.
From RJ Eskow:
Here are the first results from after-vote polling in Massachusetts: By a 3 to 2 margin, Obama voters who voted for Brown thought that Obama's reform bill "doesn't go far enough." And those Obama voters who didn't bother voting felt that way by a 6 to 1 margin. 82% of Obama voters who went for Brown (and 86% of those who stayed home) support a public option. And 57% of Brown voters said that Obama is "not delivering enough" on change.
In this stunning victory for progressives that sent a sudden shocking a wake-up call to timid Dems in Washington, it's ironic that talented, passionate progressive Dem Martha Coakley wound up being sacrificed as collateral damage.
