Not sure if matters at this point. Cruz & Trump supporters should be pretty locked in on their candidate by now.
It's kinda like driving by a car wreck when Trump says something like this as you know Cruz supporters are going to squeal and gnash their teeth. You just can't help taking a peek.
I think back to a memory of when I was growing up on a farm. During harvest time, we were putting grain in the bin. My sister and I were standing on the tires of the gravity box trailer watching the grain drop down to the door of the gravity box. From there it would drop into the auger which would carry it into the bin.
There was a large beetle of some sort running up the slope of the grain to keep from getting sucked out the door. He kept running as fast as he could but whenever he'd get close to the top of the slope, the slope would avalanche down and he'd find himself almost at the brink of getting sucked out again. After watching this for about 10 minutes, my sister looked at me and said "Gad, what sport!" I think that phrase applies quite well to a lot of the whole primary season process.
