Last night, there was a thread that he was going to endorse Gingrich.
Much trumpeting on FR about how valuable it would be. What a difference a day makes, eh?
One comment, by a prescient FReeper was "Trump's words have a short shelf life". My guess? Regardless of who he endorsed, it will be forgotten by Monday.
The only thing that I dislike is that Trump will wait until a winner is obvious, then back him. That doesn't bode well for Gingrich.
The term for this is "confirmation bias", and yes, there's lots of it here.
