Former House Speaker Newt Gingrich (R-Ga.) said Sunday that even though he had endorsed Sen. Robert Bennett, his ousting last weekend at Utah's GOP convention was a "sign of anger of the American people."

"Bennett is a very reasonable person," Gingrich said. "I think they wanted someone to come and fight."

The speaker said on "Fox News Sunday" that he expected the voter anger to carry through into the fall.

"I think voters are very upset and should be," he said, predicting that Republican Meg Whitman would win the governor's seat in California.

Gingrich also commented on the race between Democrats Arlen Specter and Joe Sestak in Pennsylvania, with an aside to former GOP Specter.

"I did one of his last Republican fundraisers for him and always wished he returned the money," he said.
