I doubt it... Most people get their news from ABC, NBC, CBS evening news. Most people aren’t engaged in the political process this far in advance. That’s why Colorado didn’t revolt when they first announced no primary. So unless the Trump Campaign can get this info out to the masses, and keep it in the forefront of the news cycle, most voters will stay oblivious — until it happens to them, in their own state. And Cruz knows this about people.
Bur one third of Trump voters said they wouldn’t vote if the nominee wasn’t Trump. Those are paying attention.
With 47% voting for the democrat, no matter what - even if she’s in a jail cell on voting day - a small percentage of Republicans sitting out the election or writing in Trump will hand it to Hillary. Cruz will lose.
