The Bernie Biden debate

I'm watching the debate right now and Joe has not melted down, just made a few minor mistakes, as did Bernie. I don't see that the debate will have much if any change on the voting behavior going forward. Yes, they have the same differences in policy that were again reiterated. And yes, I still think Bernie's policies are far better, especially on climate action. But those issue differences have not helped Bernie so far and this debate is unlikely to change that, given most voters are not following those differences that closely.
