Opponents of health care reform made their voices heard at town hall meetings across the country this month. Now supporters of a key Democratic proposal are answering back with their wallets.

In little more than a day, Blue America PAC has raised over $140,000 on the fundraising site ActBlue to reward liberal Democrats for their support of a public option. That's the largest 24-hour haul of any single fundraising page in the site's history, according to ActBlue spokesman Adrian Arroyo. A similar campaign by Blue America last year to raise money around the FISA bill ended up bringing in more than $350,000.

Spurred by a coalition of left-leaning blogs led by FireDogLake, more than 2,000 donors have given so far to 65 congressional Democrats, for an average contribution of about $65. Top recipients include: House Financial Services Committee Chairman Barney Frank of Massachusetts, current toast of the progressive blogosphere for his pugnacious response to health care protesters; Eric Massa of New York, who became a target of Republicans for saying he would vote against the wishes of his district on reform; and Lloyd Doggett of Texas, who was confronted earlier this month by angry protesters in an Austin parking lot.

Arroyo described the effort as an outgrowth of the recent Netroots Nation conference, where the focus was on turning grassroots energy into policy change. "This is a way for small-dollar donors scattered all over the United States to make their voices heard in Washington," he said. "The idea is that this really communicates to these people, to these representatives, that this is a priority issue for this community."

Progressive activists -- as well as the Democratic National Committee's Organizing for America -- have struggled recently in adapting the tactics pioneered by the Obama campaign to influence the slower-moving and less accessible legislative process.
