The reality is the Democrats wanted to set these rules because they were afraid that Donald Trump would get in a jab at Biden in the middle of the debate that basically put Biden on the floor. That's what they're afraid of. They're afraid he's going to sneak in and that Joe Biden would start fumbling his words and Donald Trump would then say, well, there he goes. And that would be the end of it. That's what they're really trying to stop. That's what they're doing with the mics. But again, the pre-spin shows how afraid the left is of this debate. CNN's Kristen Holmes doing the same thing.
