Gay activists — some of whom have tried to prove Crist is gay — are sure to howl about using homosexuality as a smear in and of itself.

In one way or another, the case has roped in every high-level Republican Party official who served while Crist was governor from 2007-2010, before he left the Republican Party and was beaten in the U.S. Senate race by Marco Rubio.

That Senate race provided the spark that blew the Crist-controlled GOP to bits and helped expose Greer’s fundraising contract through a corporation he secretly controlled called Victory Strategies. His partner in the alleged crime, former party executive director Delmar Johnson, ratted Greer out in return for a lesser sentence.

Greer’s camp wants to make the state GOP look like a piggy bank for pols and is itching to pull in Rubio for ringing up questionable expenses on a party credit card. Greer says he was only indicted after Republicans, who control the state levers of power, reneged on an agreement to pay him a secret severance package, the existence of which party insiderslied about.

A central argument in Greer’s defense: The Victory Strategies deal saved the party money because, in 2009, he replaced one-time fundraiser Meredith O’Rourke — now a Mitt Romney fundraiser — who was earning $30,000 monthly to raise gobs of party money. So if Greer saved the party money, how could it claim it was ripped off? Republicans point out the Victory Strategies deal was secret and sneaky. The problem with that argument: Party politics and finances (including the Democrats’) are secret and sneaky.

Regardless, it’s difficult to believe these latest claims are true.

Greer has never mentioned them before and, along with other one-time defenders of Crist, once explicitly told me (as did Crist himself) that the former governor isn’t gay.

When Crist’s political opponents in 2006 tried to steer reporters to his alleged gay lovers, none would confirm having a relationship with Crist. The overwhelming evidence then pointed to Crist being a heterosexual bachelor who had loads of girlfriends. Indeed, evidence surfaced that Crist might have fathered a child out of wedlock — which he denies as well.

Judging by Greer’s latest claims, it looks like the issue of Crist’s sexuality will part of the state’s politics.

So pull out the popcorn, gawk at what Crist and Greer have wrought and remember: just when you think we can’t shatter the ceiling of weird or fall through the ground floor of tawdry in Florida, stuff like this is bound to come along.
