Yes, I Have zero worries about this at all.
She'd eat him alive.
Are Democrats really going to make the same mistake as Republicans and underestimate Trump? Debating against someone who will make things up on the spot, insult you, then claim victory is hard. I imagine an exchange something like this:
Clinton: (two minutes of well scripted thought out policy)
Trump: "everything she just said is a lie. Americans know they can't trust Hillary just look at her poll numbers. They've known her for 20 years and think she is a typical politician and liar. With me American will win again. With Clinton America lost to Russia and lost to the whole middle east. We need an outsider to stand up and make America great again."
(half the room claps Trump declares victory)
