I won't try to word this in the style of a debate moderator. I'm going to put this much more bluntly and you can just imagine a neutral-sounding version with appropriate foundational clauses. I'm just conveying the core idea.
Governor Pence, you are a respectable, honorable man. How could you squander your hard-won reputation to prop up the monster that is Donald Trump?
There should be a corresponding question for Tim Kaine. Like Pence, he's got a more honorable reputation than his running mate and he's on the ticket to lend respectability to a person who could be called a monster... who has been called a monster.
2 monsters. It's like an old horror movie...
We get what we want in a democracy. And it seems we wanted a horrorshow. Too late to find another show. Yes, there's nice little Timmy and Mikey, with their little show tonight. But all that matters is what they will have to say for themselves as they prop up a monster. What are you doing with that monster?
