And which one of them is rational? This is like supporting Mussolini or Torquemada, as far as I can tell. People are supporting Cruz just so Trump doesn't have enough delegates for a first round victory at the convention. Cruz certainly won't have enough. Besides, plenty of Republicans would never vote for Cruz, either.

Then they can pick somebody a majority doesn't despise. Like Kasich or Ryan. Doesn't matter much in the Presidential race: They are doomed anyway it unwinds, unless Hillary dies and Bernie goes nuts with Leninist rants about "Each to his ability".

The people who run the Party just want a decent guy to bring out the vote for Senators and Representatives. Trump or Cruz will not do that.
