His supporters will argue fuss and fight in the Iowa caucuses and not vote enough to let him win.
Rand Paul will likely win, if not Ted Cruz.

This will resound in New Hampshire and I expect a desperate 'the Donald' to faux pas his way to another loss in the Granite State.
At that point, all bets are off in South Carolina and a loss there would reduce Mr. Trump to the level of... The Apprentice.
