I have a feeling that Crist is splitting the rat vote. That is until Meek catches up to him in the polls, which I suspect will be soon. When, and if, that happens, any support the bastard had will disappear.
Of course he is if hes splitting that endorsement. Would Meeks withdraw? Would the dems want the embarrassment of not fielding a candidate for a senate seat? It may help Crist some if he did but it may energize people to vote against him as well.
