Anyone not voting for Trump is voting Hillary.
I’m not voting for Hillary. I’m voting for Cruz.
In the general election that is correct. In the primary, no.
I agree that rational, reasonable people should vote for whichever of the 2 wins the nomination, Trump or Cruz, in the general election. I've seen plenty of Trump people here say they will not vote for Cruz in the general election if it comes down to that - which is just as dumb as refusing to vote for Trump in the general election if he wins the nomination. #NeverTrump is just as silly as #NeverCruz.
