You’re assuming she has debts to pay and I also saw your post to Frantzie. You seem open to the thinking that he has ‘dirt on her.’ You lost me there.
You’re also making some assumptions regarding the Crist/Rubio race. There’s no reason to believe that Rubio has asked for her endorsement.
Sarah is free to do whatever she pleases in her support for McCain. I personally hope she will winde it up this month and not go back to Arizona.
I really don’t know the reason for her energetic support for McCain. She hasn’t addressed the issue of his big-government, leftist positions and instead has simply repeated over and over that he’s a warrior who hasn’t bucked his party on health care. (When she’s otherwise called for us all to back more conservative candidates in the oprimaries.) She’s entirely free to endorse whomever she wants and all other supposed Republican frontrunners for ‘12 have endorsed McCain as well.
But our country is suffering grievously now for the Pubbies having backed McCain in ‘08, and for conservatives to take full note of her backing him now is IMO only fair and very much called for.
