Two Republican sources said today that even as former Florida House Speaker Marco Rubio campaigns for retiring GOP Sen. Mel Martinez's Senate seat, he has been calling around to top Republican donors and activists in the state to discuss the idea of switching from the Senate primary against GOP Gov. Charlie Crist and into the open-seat race for attorney general, where a serious Republican candidate has yet to emerge.
Rubio has issued a bunch of weird, jokey non-denials on Twitter. It would suck if he dropped out, but I wouldn't be surprised if he started bailin' like Palin.
UPDATE: Some more claims by various media outlets that Rubio is "denying" his interest in the AG spot, but the only thing his camp has said is that "Speaker Rubio is an active candidate for U.S. Senate" and "He is squarely focused on winning this campaign for Senate." Those are not denials.
