If Trump wins the nomination, I will be voting for the most conservative candidate on the ballot, who will definitely not be Trump.
I think that’s fair. I do the same thing. Usually GOP, sometimes a different party. I detest the GOP. My motto has always been that when a party loses, it’s the party’s fault, not the voters. And I fully respect each voter’s right to reject a candidate they find objectionable, even if the vote is just a “protest.”
