I’m not certain, but I suspect they’ll have to pass on voting in the GOP primary to do that, and this year that’s not likely to happen.
Incidentally, one good thing about Sanders running is that it will tend to keep Dem voters from messing with the GOP primaries as long as he’s doing okay. Once it becomes a certainty that Hillary has dispatched Sanders, the Dems will cross over and mess with the GOP wherever they can.
Yeah. But since they think Cruz is the most unelectable, they'll probably vote for him so that Hillary won't have to run against Jeb Bush, whom they fear.
