Trump is in a position where the rule of law scarcely affects him, regardless of what a judge sentences him to, because of the sheer quantity of political capital backing him. If this happened, he would spend a couple months in a cell and nothing else, at best. So if you think he should be arrested based exclusively on the law itself and no other reasons, sure, that’s justified. But I’m talking impact, here.
I think the overall impact would be negative for the reasons given above. He’d face scarcely any truly proportionate punishment, would learn nothing, would lose nothing, and his supporters would become even more rabid. And all that would mean the political calculus for “is it worth it to commit fraud” either doesn’t change or goes even further in favor of “yes.” What’s the point, then, besides to make us feel a bit better until he inevitably gets released?
Technically yes, since the convicted felon is the president-elect and has literally changed the power balance of the judicial system already.
Really though, it all comes down to risk. The more frenzied his base becomes, the more they let him get away with, and thus the more he will take advantage of that. Normally, I wouldn’t care about this, because if Republicans aren’t given this “feral consent” they’ll manufacture it themselves. But I pause because the actual benefits of this are so slim as to measure up poorly against even this low-level con. I mean, he’s in jail for a couple months — so what? Does that stop him from doing much of anything? Will he even care, when he knows he’ll leave it with just as much power as he had when he entered?
Were it that he’d lost the election, I’d feel differently. But we don’t live in a sane world. What do we actually get out of this?
