Senator Joe Biden slammed John McCain and said while he has been a "maverick" on some issues, "he has been no maverick on the issues that matter to people lives."

Biden blames some of the economic crisis on deregulation policies that John McCain supports. Governor Sarah Palin tried to paint Barack Obama as "dangerous" for being open to meeting with rogue leaders without preconditions.

"An issue like that taken up by a presidential candidate goes beyond naivete and goes beyond poor judgment," Palin said.

"A statement that he made like that is downright dangerous because leaders like [Iranian President Mahmoud] Ahmadinejad, who would seek to acquire nuclear weapons and wipe off the face of the earth an ally like we have in Israel should not be met with without preconditions and diplomatic efforts being undertaken first."

In a debate last summer, Obama said he would meet with Ahmadinejad without preconditions. He later clarified to say he would not meet with him without preparations.

Palin also said Obama's campaign does "too much finger-pointing" to be serious about its call for change.

"There have been huge blunders in the war. There have been huge blunders throughout this administration, as there are with every administration.

"But for a ticket that wants to talk about change and looking into the future, there's too much finger-pointing backwards to ever make us believe that's where you're going," she said.
