1) Biden looked and sounded terrible.
2) Biden fell back on talking points far too often.
3) Trump lied through his teeth, and slathered on the exaggeration, boasting, and hyperbole as usual.
4) Trump dodged and weaseled away from every question that he didn't want to answer.
But what's the bottom line? I think Trump will be adjudicated--by whatever means--as the "winner" of this debate because he looked more vigorous. Never mind that he behaved like a lying asshole. That isn't important--unbelievably.
This was an expected result in Europe: Ladbroke's had Trump at -165.
Will it make any difference? No. There's not a single voter on either side who will be swayed by this nonsense. So it was nothing more than bad political theater.
