This is standard political process.

You NEVER respond to a challenge from an opponent.

Trump and Biden both “demand” stuff. The demand is the basis for making an accusation in the form of a challenge. It makes the media turn and say, “Well?””

If anyone thought this stuff was serious, this must be the first campaign (from selectman to President) where you’ve ever paid attention.

Yeah. Biden’s been in office 180 years. He knows better.

Correct. Trump knew that Biden would not accept a drug test. Its gamesmanship. But Trump did reinforce the notion with the American people that Biden probably WILL need some kind of medication to last 90 minutes on stage with Trump. Correct me if I'm wrong but I don't think Biden's spoken more than 30 minutes at a time since he was nominated and even less time than that without a teleprompter.

Now I don't expect to see Biden melt down like others are predicting he will. I'm also sure his campaign team have already been given the questions that Chris Wallace will ask him so Biden has had all this time to memorize his platitudes and canned responses. Most likely, he's also memorized a few good zingers to throw at Trump.

So I'm expecting Biden to be able to hold his own tomorrow night.

But Trump has all the advantages. He's got tons of practice handling hostile lines of questioning, has the ability to talk for hours unscripted on virtually any subject, and can come up with zingers on his own in real time.

Biggest advantage Trump has is four years of achievements. He needs to pound away at the fact that Biden has spent a half century in public office and what has HE done? NOW he's going to lift his finger and do something?

Biden campaign DID respond to it.
