Here's a better question - why isn't a guy who supported Hillary being a wimp?
Is he, perhaps, having an effect on the Republican vote split? Check.
Will that reduce the overall number of available votes for other Republican candidates? Check.
Figure out how the rest of those votes play out, and you'll know, one way or the other, why Trump is being so brave.
(Hint: He's a billionaire, with a "b." He doesn't live in your world, and he doesn't live in the world of millionaires, either. Remember that when you're trying to figure out his motivation.)
What's my opinion? Given that Cruz is saying all the right things and WAS the rising star on the Republican side, call me "skeptical as hell."
Beware another Perot - it's how the Clintons got elected last time:

Reagan used to be a democrat.
Poor Trump having to hang with those arch criminal poor scumbag Clintons!
Because the GOP 'leadership' REFUSED to pay attention to him!
How many times are we going to get the football jerked away before we wise up?
