I watched the entire debate in the U.S. Senate on Tuesday, culminating in a 56-44 vote affirming that second impeachment trial of Donald John Trump is constitutional despite that fact that he is no longer the president. It was probably the lowest point for American politics in my lifetime.

There shouldn’t have been a debate on this at all, since it’s obvious that when a sitting president is impeached by the House, the Senate is obligated to hear the case even if the president’s term in office expires before or during the trial.

The issue is whether Trump should be barred from holding any future office of trust, honor or profit. It’s a live issue, as Trump is eligible to run for president again and he could also be appointed to a position in a future Republican administration.

If you watched the legal presentations, you know that the ex-president’s lawyers did not acquit themselves well. But even if they had proved competent, they did not have any available coherent argument to make. The vote was not on Trump’s guilt or innocence, but only on whether it is legal to have a trial at all. Forty-four Republican senators listened to the evidence and then said ‘no.’ This is a deeply depressing outcome.

There are a lot of bad precedents we’re seeing here. For one, this vote strongly presages an acquittal for Trump, likely by an identical or very similar margin. After all, it’s hard to convict someone in a trial after you’ve argued that the trial is illegal. And Trump most definitely should not be acquitted lest future presidents believe they can with impunity set a murderous mob loose on Congress in an effort to overturn a lost election.

But it’s also terrible that the vast majority of Republicans treated the constitutionality question as if it were a partisan procedural vote. This was much more important than that. They just established that it is the Republican Party’s position that a president cannot be denied the right to run for office again even after illegally attempting a coup. This is throwing in with fascism in a very explicit way, and it’s incredibly dangerous.

It’s also offensive. Cowardice is never attractive, but unnecessary cowardice is doubly obnoxious. After all, if a Republican senator is ultimately going to acquit Trump regardless of what their conscience tells them, they’re under no obligation to also vote that the entire trial was illegitimate. Even Mitch McConnell voted this way, and he certainly knows better. He’s on the record saying he wants to hear the evidence before he decides on guilt or innocence, but now he’s flipped to saying no possible evidence could be compelling because Trump cannot be tried.

I’m used to the Republicans making bad faith, dishonest arguments. I’m used to them being scared of their critics on the far right. But this time they were attacked in their place of work while they were trying to fulfill their constitutional duties.

And they still won’t learn anything from this. They don’t conclude they let things go too far. They don’t decide to take the matter seriously. It’s not a surprise, but for me this is a new low.

I think there may actually be no bottom with these folks.
