Washington ? Vice President Dick Cheney on Sunday dismissed suggestions that the Bush White House, hampered by a weak response to Hurricane Katrina and stumbles on policy questions, needs a shake-up.

“I don’t think we can pay any attention to that kind of thing,” Cheney said on CBS’ “Face the Nation.” “The president has got a job to do. … He ignores the background noise that’s out there in the polls that are taken on a daily basis.”

Bush’s job approval in March was at 37 percent, which tied for his lowest rating in the AP-Ipsos poll. Senior Republicans and others have said the Bush team may need an infusion of fresh blood and ideas.

Cheney, in a rare Sunday morning television interview, told CBS that he heard similar grumbling 30 years ago when he was chief of staff for President Ford.

“Administrations go through peaks and valleys,” he said. “When you’re down in the polls you’re going to take shots that you don’t deserve, and when you’re up in the polls you’re probably going to get praise you don’t deserve.”
