It might be that more lefties apply to be on QT, although to be honest any normal decent moderate person can see that Trump is a nasty piece of work.
They do seem to have a left wing bias. Jeanette Winterson has been on Any Questions (R4) at least twice, maybe more times, and routinely bullies and shouts down those she disagrees with. Last week she shouted down a Tory MP when it was his turn to answer a question, not allowing him to have his say, and the chairman did not intervene to allow him to speak. Then again, he's a Tory, so not nice, and it's all for the good isn't it?
Ooooooh the irony.
Well, what irony?
Ok, I'll explain though you've had enough time to find it.
