The clear loser in this debate was any and all of the people watching.
We already knew interrupting, talking over and attacks, whether made up or real, were Trump's way of debating as he gets results with it. The louder he is, the more unclear the opponent is.
The debate organization has said they are re-working their model to allow for smoother debates in the future. Short of putting each candidate in their own soundproof cube and shutting off the mic and camera on the opponent while a candidate has a chance to speak, I don't see anything changing.
Perhaps a debate via zoom would work better.
The only thing of all this that upset me was Joe dropped down to Trump's level after being brow beaten. Wrestle with pigs and you'll get dirty too.
