Do you think Trump won the debate with Bidin?

It wasn't really a debate.

A debate should have the contestants directly addressing each other, not the moderator or audience.

We haven't had a decent presidential debate in a while.  Not since modern political campaigns started gaming the debate system, and so-called moderators started acting like political henchmen.

IMO, they've lost any value they may once have held.

Yes.  President Trump won.  He went in, saw the Swamp, and went after Biden.  You can't appease the Swamp.  They have dug in too deep.  All you can do is fight them and President Trump is a fighter.

I think it was a toss up. I'm an undecided voter and I came away from the debate disliking both candidates, and still undecided.

Nope. No one said anything. Trump came out even gaining no advantage, he sounded like Trump. 

Biden didn't say anything but he didn't stutter and bumble to much so that was really all he had to do. He just had to appear lucid and he did so that was a win. 

Nope because he came off as an inconsiderate jerk who won't abide by the rules he agreed to!.

Just as he'll probably do again if they debate.
