While Republican presidential candidate John McCain and his running mate Sarah Palin enjoy a bump in the polls, Democratic presidential candidate Sen. Barack Obama and Sen. Joe Biden show evidence of a camp divided.

In an interview on the “Today” show this morning, Obama appeared to chastise his running mate for disagreeing with him on the feds’ AIG bailout plan.

Obama told NBC’s Matt Lauer that he doesn’t expect the mortgage plan to cost the full $700 billion right away, and all the money won’t be lost.

“Does that mean that I can do everything that I’ve called for in this campaign right away?” Obama said. “Probably not. I think we’re going to have to phase it in. And a lot of it’s going to depend on what our tax revenues look like.”

Obama then launched into an attack on McCain for initially opposing the government’s bailout plan, saying, “I think what has been clear during this entire past 10 days is John McCain has not had clarity and a grasp on the situation.”

But Lauer pointed out that Biden also opposed the bailout plan. To which Obama replied, “I think that in that situation, I think Joe should have waited, as well.”

On Monday, Biden launched a critical blow of his own directed at Obama.

In an interview with “CBS Evening News,” Biden said he objected to a television ad — approved by Obama — which depicted McCain as an out-of-touch, computer-illiterate old man.

Biden said he disapproved of the ad and appeared to criticize his running mate for the negative tone of the campaign.

“I thought that was terrible, by the way,” Biden said. “I didn’t know we did it and if I had anything to do with it, we’d have never done it.”
