A couple weeks after airing ads attacking John McCain for his escalation plan, MoveOn is back up on the air again -- and this time, the group is targeting GOP Senators for stalling debate on the anti-escalation resolution in the Senate. The $130,000 ad campaign -- which specifically targets GOP Senators John Warner, Sam Brownback, John Sununu, George Voinovich, Arlen Specter, Mitch McConnell and Elizabeth Dole -- will run nationally on CNN and in some local markets in D.C., New York, New Hampshire, Kansas, Maine, and Virginia. The ad slams the Senators hard: "They're willing to send tens of thousands more troops to face danger in Iraq, but they don't have the courage to face a vote." View it here.
