Let’s think logically. Trump supporters are folks who go out in all kinds of weather, drive great distances, stand in line forever even knowing they might be in an overflow room, to hear Trump speak. Of course they’ll show up for a caucus.....it’ll be like a rally where they’ll be surrounded by like-minded people.
I suspect you are probably right. If so expect great rending of garments and gnashing of teeth on the part of the Cruz or Losers. If on the other hand Cruz wins they will be insufferable for about 8 days until Trump buries the NH field in an avalanche.
