Doesn't Gingrich realize he's already in a terrible muddle that he cant get out of with his campaign?

What Gingrich apparently doesn't realize, but someone should really point out to him, is that he has already lost. It's just not on paper yet. He should get out of the race before he embarrasses himself furthur. I don't know why this man ever got into the race. Didn't he have smart enough advisors to tell him not to run, that he had no chance?
