“It’s a huge sum, and the clearest signal yet that any Democrat who helps Republicans filibuster health care reform will face an enormous backlash from the grassroots,” writes Ruben. And now, working in conjunction with Howard Dean’s old organization Democracy for America, MoveOn is starting a drive to take away the committee chairmanships of any Democrat who fails to live up to MoveOn’s progressive standards. “Many of these senators hold coveted committee chairmanships that give them significant power within the Senate,” Ruben writes. “Our friends at Democracy for America have launched an open letter urging Senate Democrats to strip committee chairmanships from any Democrat who filibusters health care.” Ruben says that more than 66,000 MoveOn and Democracy for America members have pledged to contribute.
