No doubt all right-thinking Americans will tune in the Democratic presidential debate tonight. We’ll be watching, if for no other reason than to see how the candidates hold up under questioning and attacks. I’m not betting on Joe Biden coming in, and will be surprised if he shows up at the last minute tonight, but what do I know? I haven’t paid much attention to the news today. I think Joe will definitely step in if Hillary stumbles, but I don’t expect her to do that.
