The St. Petersburg Times says Sen. Mel Martinez is quitting the Senate:

Martinez won't seek re-election; Sink will

U.S. Sen. Mel Martinez plans a major announcement in Orlando shortly and a highly-placed Republican source says Martinez will announce that he's not seeking re-election and that he may leave his seat in advance of the end of his term in 2010. That would open the door for Gov. Charlie Crist to appoint a replacement in advance of a wide-open Senate race in '10.

Is Martinez quitting so Gov. Crist can appoint Jeb Bush? On Saturday, far-right Newsmax published an interview with Jeb urging Republicans to form a "shadow government" (h/t Faiz). Does Jeb want to be the Shadow President?
