The convention will be great entertainment!!!
The ironic thing is, this isn't even about issues anymore.
Trump and Cruz are pretty much on the same awful page when it comes to issues. Heck, Kasich is 90% of the way with them. If the GOP Electorate were smart, it would get behind Kasich who would STILL give them 90% of what they want in the very small window of the first two years of a Presidency (the only time ANY president really gets anything done) because he has a better chance of beating Hillary than Cruz or Trump do.
This has become about cults of personality. Neither of these guys can beat Hillary. Their negatives far outweigh their positives.
The GOP Establishment has figured this out, and has concluded that if they nominate Cruz, and he loses, he will do it without beclowning the whole party AND will finally put an end to the whine that if "you only elected a real conservative, you'd win."
