Trump needs the ground game.
I think he also needs to present a positive message of his vision for America. “Here’s where I want us to be in four years.”
He’s not giving the voters a ‘feel good’ reason to vote for him.
He was in the beginning but then he went for Cruz and it got ugly.
He needs to get back on message. I do think he's smart enough to see the mistakes/problems from Iowa and correct them.
I'm not sure he recognized just how important the ground game was. Your have to not only show up, they have to counter the others at the caucus.
I've been up against Code Pink and illegals marching in the streets of San Diego screaming in my face......I'll bet I could handle a caucus :D
Bingo! You nailed it.
