The Campaign for Jobs and Economic Recovery, a coalition of liberal groups formed to lobby for passage of the stimulus bill, today released 21 new radio ads targeting Republican lawmakers in both chambers who voted against the legislation. The group also released a general pro-stimulus TV ad in D.C. and on national cable. That brings the total number of spots the group has run to 40 since mid-January, for a cost approaching $800,000.

But judging from the list of 21 targeted Republicans, the group could have saved its money for the next legislative battle; even if every representative and senator targeted by the Campaign again votes against the bill, the legislation will still pass both chambers. Further, two of those targeted aren't even running next year: Ohio Sen. George Voinovich has announced he won't seek another term in 2010, and Nevada Sen. John Ensign isn't up for re-election until 2012.

"We feel that it's important that it's not just passed but that it gets a broad support base, and we really think that in some of these districts, it's really important they have this package," explained Lauren Weiner, a spokeswoman for Americans United for Change, one of the groups funding the campaign. "Our campaigns aren't strictly political, election-oriented."

MoveOn.org this afternoon expanded the ad onslaught with a radio spot attacking Texas Sen. John Cornyn that it plans to run the rest of the week. The buy has some symbolic resonance because of Cornyn's position as head of the National Republican Senatorial Committee, but -- like Voinovich and Ensign -- Cornyn voted against the stimulus bill on Tuesday, he is likely to do so again, and he won't face re-election next year.
