Jeb Bush: Campaign 'not on life support'

Message from Jeb Bush: His presidential campaign is still alive.

"It's not on life support," Bush told reporters Thursday, the day after his widely panned debate performance raised questions about the state of his campaign.

"We have the most money," he said. "We have the greatest organization. We're doing fine."

The debate, coming in the wake of campaign cutbacks and other stumbles, led to pundit speculation that Bush may not be able to survive the race much longer -- speculation the former Florida governor quickly shot down.

"There are eight more debates,"  Bush told reporters. "There's ample time to do what candidates do."

He added: "The end is not near -- memo to file. Life is good."
