Cruz supporters would need rubber rooms, IF Trump were the beneficiary, of the PTA style delegate selection. So Cruz wins a few delegates, but will not win the state come November... And they call Trump supporters low information voters.
If you think the Donald can beat Hillary just by tweeting a few insults, you may want to check the 50+ most recent polls concerning a potential match up with Hillary. The most recent show Hillary up by 12%. Trump won just two of those polls, neither by more than the margin of error, and ‘none’ in 2016.
Remember, IF he wins his home state NY, as expected by the margin expected, it will be the ‘first’ time he has broken the 50% mark in any state, and that’s just of the Republican party, with some Dem crossover in open primaries. ...think Electoral College.
