If you would vote for Trump as 2nd choice, then you're not really a "Cruz or Lose" person. A "Cruz or Lose" is somebody who would rather see the Democrat win, than vote for any Republican but Cruz -- something like what we saw here in 2012, where I recall people saying they would rather Obama win, with the idea that boycotting "RINOs" would force the Republican party to nominate a true conservative next time.
For me, my original first choice was Scott Walker. I thought his experience as governor, and his willingness to fight the Democrats during Wisconsin's "Right to Work" fight, would make him a great president. But he turned out to be not charismatic enough on TV to appeal to many people, plus he fell down on immigration, so I had to look for a second choice.
I’m Cruz or loose boots on the ground. And what it means is that if Cruz doesn’t win tis country WILL lose. He is the only one with Constitutional experience which, now more than ever, will be needed to appoint Constitutionalists on the court.
