Sen. Jim DeMint (R-S.C.) said it could happen. The tea party group FreedomWorks is polling on it. And conservative pundits are pushing for one.

Now former Alaska governor Sarah Palin is saying she would “help” in with a brokered convention.

“We could be looking at a brokered convention,” she told Fox Business Network on Wednesday night. “Months from now, if that’s the case, all bets are off as to who it will be, willing to offer up themselves up in their name in service to their country. I would do whatever I could to help.”

A convention without a nominee is very unlikely, and if it did happen it would be total chaos.

Given that Palin has faded from the political scene in recent months, it could provide her a chance to return to relevance. In theory.

Palin thrives on dissatisfaction with the current presidential field, and the longer the Republican Party fails to coalesce around a candidate, the more attention she will get as a standardbearer for unhappy conservatives.

But it’s a losing gambit, for a couple reasons.

One, her clout is dubious. Her popularity peaked long ago, and the supporters she does have won’t necessarily follow her lead. When Palin praised former House speaker Newt Gingrich on her Facebook page, many of her fans balked. While Palin can amplify tea party concerns, she doesn’t speak for or carry that group.

Two, she isn’t what people are loooking for. The names that come up when talk of a brokered convention surfaces — as either candidates or potential dealmakers — are relatively moderate politicians with broad support: former Florida governor Jeb Bush, New Jersey Gov. Chris Christie, Indiana Gov. Mitch Daniels. A polarizing figure like Palin is hardly in the mix. (Ezra Klein argues that whoever does get the nod will be on a suicide mission.)

Palin is good at seizing on trends, however, and her decision to latch onto the “brokered convention” talk is a sign of increasing interest in the idea.
