I think Shapiro wants to know answers to some of the things she says. If she gave Shapiro legitimate answers, she'd have nothing to worry about. If she didn't, then obviously she's making herself look bad. Shapiro would capitalize on it too and would be stupid not to.
She says some things I think a lot of people want clarified.

Reading through that and some quick google searches I generally disagree with a lot of things she stands for. But she isnt someone I care about since she has very little to do with stuff here.
Maybe that is some of the reasons he wants to debate with her but I am sure he still wants to prove her wrong. She does owe her constituents answers and clarification. Politicians should be very open and not leave things to guessing and do things behind closed doors(one of the reasons I strongly dislike the SLC mayor). But she definitely does not owe him anything. He lives in LA right?
