Another bailout of the banks would not be politically possible, in part due to a perceived damaged leadership of Senate Banking Committee Chairman Chris Dodd (D-Conn.), one of his Senate colleagues said Thursday.

"In other words, if we have the TARP IV, you couldn't get it passed with Chris Dodd's problems as head of the banking committee in the senate and the public outcry on just the bonuses," Sen. Jim Bunning (R-Ky.) said during an appearance on the Fox Business Channel.

During the interview, Bunning, who like Dodd faces a potentially difficult reelection battle, also joined the bandwagon calling for the resignation of Treasury Secretary Tim Geithner.

"I didn't think he was qualified for the job because of his involvement in TARP and a seat at the table," said Bunning. "And then of course, he hasn't done anything to ease the burden."

Bunning joins several House lawmakers and Sen. Johnny Isakson (R-Ga.) in calling for Geithner to step down.
