Liberals Pledge $3.5 Million Against Dems Who Filibuster

The left's pressure on centrist Democrats has steadily grown since the health care debate began but MoveOn.org and Democracy for America today launched the most direct threat yet: together, they've secured commitments from 66,000 members to donate a total of $3.5 million to support primary challenges against any Democratic senator who joins a Republican filibuster to block an up-or-down vote on health care reform. The groups announced the commitment in a fundraising email to supporters today.
