Sarah Palin confirmed on Greta Van Susteren's show last night that she's very much planning to show up and speak at the National Tea Party Convention in Nashville, despite the distinct odor of Scam the whole affair is giving off.

Palin: Oh, you betcha I'm going to be there. I'm going to speak there because there are people traveling from many miles away to hear what that Tea Party movement is all about and what that message is that should be received by our politicians in Washington. I'm honored to get to be there.

This, even as some of her fellow wingnuts are catching the same whiff -- namely, Reps. Michele Bachmann and Marsha Blackburn, who have pulled out of the event:

In separate statements, released by their congressional offices, the lawmakers said that appearing at the convention might conflict with House ethics rules. But they also said they are concerned about how money raised from the event will be spent.

Palin last night had no such concerns -- and said no one should be concerned about that big wad of cash the convention organizers are paying her:

Palin: The speaker's fee will go right back into the cause. I'll be able to donate it to people and those events, those things that I believe in, that will help perpetuate the message, the message being: Government, you have constitutional limits. You better start abiding by them.

Hmmmmm. It sounds like we're going to have to rely on Sarah's say-so when it comes to how she actually spends the money. Smells even more like Scam, doesn't it?

Of course, the whole scenario, as David Corn explored with Keith Olbermann last night, is developing into quite a fiasco -- mainly because Tea Partier and Birther J.D. Hayworth has decided to challenge Palin's former running mate, John McCain, in the Arizona Senate primary.

Palin is staying loyal to McCain. This has outraged the Tea Partiers, as Alan Colmes points out:

She has now chose to align herself with several bad actors. What should this be called, the Rinoization of Sarah Palin. [...] She is certainly entitled to write a book and make money for her and her family, but other than what has she has done to support Republican and patriotic candidates. … Perhaps, Sarah was too busy talking to her agent about her Fox deal. Where the hell was Sarah?

This is what you get when you build a movement around paranoid right-wingers. There is probably no faction more historically famous for viciously turning on each other in struggles over money and power than right-wing populists.

Couldn't happen to a nicer bunch.
