It’s not a complicated answer:
“If I am the nominee I will be voting for myself. Otherwise I will be voting for the Republican nominee. I will not be voting for the Democrat nominee or any third party candidate. I will not be a pantywaist like Christie Todd Whitman, for example, who can’t bring themselves to vote for the Republican nominee. Again. I will be voting for the Republican nominee, whether it be myself or some other candidate, including Donald Trump, should he be the nominee.”
Trump wouldn’t answer the question either. Lol
