Newt Gingrich has abandoned Illinois, saying it's a two-man race between Mitt Romney and Rick Santorum, but he still says he's taking his campaign to Tampa.

Probably.

But when asked Friday what conditions could lead him to withdraw from the race, he says, "Probably none."

Gingrich tells the network "I have 176,000 donors at Newt.org. They want me to stay in the race."

Forget the 176,000 donors. Sheldon Adelson is the only one that counts. And he's done nothing to suggest that he's stepping forward with another $10 million to bankroll Newt.

I'm sure Gingrich would deny it, but given that Adelson hasn't done anything to suggest he's going to make another deposit into Newt's Super PAC, isn't "probably none" the first step towards "I'm done"?
