Prager is voting for Trump. He has made it clear that while Trump was far from his first choice, he is infinitely preferable to the Leftist Clinton. I can’t comment on the others, but I have heard Prager say this several times.
BTW, Prager’s career is far from over. His ratings remain at levels where they were before the campaign.
Prager’s appeal is much more cultural than political, and he will remain very popular.
