No. The problem is that pretty much everybody knows going in that neither of these guys is going to say anything new or interesting. We know their policies, we know what they believe (to the extent that Trump really believes anything), and frankly, we know that the bar for these debates could be roughly described as "coherent." There's no chance of either candidate doing anything to convince anyone of the rectitude of their positions who didn't already support them. It's just pointless.
