Nancy Pelosi (D-Calif.) is unlikely to remain Speaker of the House even if Democrats hold onto their majority, her predecessor said Friday evening.

Former Speaker Dennis Hastert (R-Ill.) said it would be difficult for Pelosi to hang onto her gavel come next January.

"I think even if the Democrats win, which I don't think they'll win, I don't think Nancy Pelosi will be speaker," Hastert said during an appearance on Fox News.

Hastert was likely drawing on some of his own experience. He was GOP speaker heading into the 2006 elections, in which Democrats won back control of the House and the Senate. He won re-election that year, but didn't pursue another term as Speaker, and resigned in November of 2007.

Pelosi's faced a trickle of eroding support among Democrats in tough races this fall. She's shown every intention of running again for speaker, though.
