Former Rep. Tom Tancredo (R-Colo.) ripped into fellow Tea Party favorite Sarah Palin in a recent interview, saying she's not "presidential" and accusing her of simply trying to sell books.

In an interview published yesterday (via GOP 12) Tancredo said he can't see Palin as commander in chief.

"I really don’t have this feeling about her as being presidential," he said. "I don’t know what it is exactly. I don’t know if the issues really are that difficult for her or not.”

Tancredo said Palin doesn't seem to be attempting to improve as a candidate and suggested that her goal seems to be to "make a lot of money and stay in the mix."

Tancredo said he's particularly upset that Palin will campaign for John McCain in his primary against J.D. Hayworth, a Tancredo ally:

She has to do this to rise in the party ranks?

“I think so.’’

So she is just as much an unprincipled politician as all the rest of them?

“To a large extent.’’

And you still love her?

“I didn’t say that!’’

Well, in your Tea Party speech you pointed out that she could finally say all those wonderful things now she’s free from McCain.

“I said: ‘Now she can tell it like it is.’ And she chooses not to.’’

But Tancredo saved his heaviest fire for McCain, whom Tancredo has long disagreed with on immigration reform, among other things.

“I don’t like him," Tancredo said flatly. "He is not a very pleasant person. He is nasty, mean; the skin of an onion would look deep compared to his. He has a short fuse, he is almost peculiarly unstable.”
