The Democratic Congressional Campaign Committee (DCCC) is launching a radio ad campaign against five Republicans who voted against the Democrats' regulatory reform bill last week.

The targets are a who's who of top Democratic bullseyes: Reps. Dan Lungren (R-Calif.), Mary Bono Mack (R-Calif.), Lee Terry (R-Neb.), Charlie Dent (R-Pa.) and Joe Wilson (R-S.C.).

The ads say the members "voted to let Wall Street continue the same risky practices that crippled retirement accounts and left taxpayers on the hook for $700 billion dollars" -- a reference to the bailout last year.

The ads represent the first phase of a new campaign. The five members will also be targeted by automated calls, live calls, and more than four million e-mails.

The DCCC did not say how much is it spending on the campaign.

UPDATE: NRCC spokesman Paul Lindsay fires back: "Being on the opposite side of Speaker Pelosi and Barney Frank is never a political liability, which may explain why more than two dozen Democrats joined Republicans in opposing this permanent bailout legislation."
