Boring debate. Clinton played it safe. Trump was bad but not inconsistent with how he's been in the past.
I don't think this changes anybody's mind.
Clinton might move up a couple of points in the polls, not because of her performance but because the debates mark the final stretch of the campaign and all those Johnson people are going to have to start getting serious.
I'm sure most Johnson voters understand the gravity of what they're doing - when you get to LV screens you're not talking to lazy, ignorant people. Clinton or Trump has to actually give them a reason to come back, time alone isn't likely to do it. Maybe Clinton did it, maybe she didn't. We'll have to wait and see.
