Megan will go on as usual and Trump will still be in his petty feud with Fox News for weeks and months - not days.
How do I know this? Because he closed his options when he said he would speak at the veterans event on the night of the debate. So even if Megan is not a moderator, he can't show up at the debate without breaking the event.
Fighting with the media directly gets the egg on ones face.
What’s amazing is that Trump is accused of not having much of a ground game in Iowa. It sure is amazing that he can put on such a huge event in such a short period of time with no ground game.
Trump is a miracle maker!
