Joe Biden weighed in on Sarah Palin tonight, criticizing many of her public comments as "just so far out there."

In an interview CNN's Larry King, Biden said he liked his former 2008 rival but couldn't wrap his mind around many of her statements.

"I like her. She's an engaging person. She has a great personality. I don't agree with what she says and I think some of the things she says are not, well...." he said, before stopping mid-sentence.

King prompted Biden to finish his thought.

"Well, you know, it's sort of like, some of the comments made are just so far out there," Biden continued. "I just don't know where they come from."

Biden also speculated on why Palin appeals so strongly to a certain portion of Americans.

"Governor Palin appeals to a group of people who are generally frustrated, feel disenfranchised, are very conservative--not all of them," he said.

"Tea Party people, but beyond that. She has appeal beyond that as well. But I don't know that it represents anything approaching a significant portion of the population."
