Adams explains that the Persuasion play is to mock each charge with a single sentence, and then go straight to a vote.
Otherwise, you allow the opposing side to bring in their heavy artillery.
I don’t think Scott Adams is right about every thing Trump. A few months ago he was saying Trump has no chance at reelection. Again, calling no witnesses seems like the worst move they could make. The Democrats already claim President Trump is going to get off just because the Senate is majority Republican. The GOP needs to lay out their case and do this right.
The accuser brings that anyway, in the accusation.
You are suggesting to allow the accusation to lie there, unrebutted. Dismiss because "even if all that is true, and for argument we will say it is, we will not remove from office."
Even if that isn't how the argument is made, that's what it amounts to. A summary "these charges are bogus" without more explanation than House GOP has already mustered, isn't much better.
The public has barely been exposed to the defense. And the public has not been exposed to certain facts in defense, such as the hard evidence that Biden is corrupt, and the hard evidence that Ukraine meddled in the 2016 election.
