I haven't really followed this closely, but what is the evidence that Crist is gay? Some guy claims to have had an affair with him? Didn't a man also claim to have had sex with Obama? Does that mean he's gay?
Dear Lord, where do we begin (not that there's mountains of evidence, it's just a really complex plotline; Florida politics is interesting)... Okay, the former chairman of the FL Repubs is a guy named Jim Greer, who is now under arrest for several felonies (organized scheme to defraud, money laundering, grand theft); he made a company that would take funds from the FL GOP and use it on his personal expenses. Greer says that Crist knew about it, people don't believe him, his attorney talks to the guy in charge of Crist's law firm (John Morgan), his attorney says that Crist is gay, had gay relationships with at least two men, paid those two men to leave the state, tried to kiss Greer, went on drunken escapades, and attempted to run over people while on a drunk golf cart joyride. Crist says that it's "a bunch of delusional lies" and that Greer is trying to extort him, and Morgan questioning why, if Crist was gay, would he try to kiss Greer (in his own words, "He (Crist) would have to be a sick son of a bitch to try to kiss Porky the Pig"), and also comparing the questions Greer's attorney was asking to be comparable to "when was the last time you [smurf]ed the neighbor's sheep", or "are you still beating your wife." After this incident, Greer accused Crist of appointing George LeMieux to the US Senate in order to keep him quiet about Gayporkydrunkengolfcart-gate.
Also, there was a 21-year-old GOP staffer (Jason Wetherington) six years ago who boasted that he had banged Crist and also said that a convicted robber (Bruce Carlton Jordan) was Crist's long-term partner. They both worked for Katherine Harris in her Senate bid. AFAIK nothing much ever became of it, but it was fodder for some documentary (
Outrage, I think it was called).
