The Dems should make a lot of noise about this pardon corruption.
It's easy to explain and easy to understand that pay-to-play pardons make a mockery of justice.
I don't disagree.
But other than being vocal about it...what recourse is there? Trump does not recognize shame, nor admit wrongdoing in any context, so it's not like he'll ever change his behavior. So what forcing mechanisms are there?
* He's not up for re-election, and so there's no accountability there.
* Congress could try to do something via legislation (e.g., require Presidential divestment into blind trusts), but 1) you'd need a veto-proof majority, which just ain't happening, and 2) would get tied up in the courts longer than Trump's remaining time in office.
* Judicial relief is off the table. SCOTUS has made it clear that bribing for a pardon is totally A-OK, because you can't ever second guess a President's core powers.
* You could try to modify or curtail the pardon power, but that would require a constitutional amendment (2/3 of Congress, plus 3/4 of all States), which also ain't gonna happen.
* And that leaves impeachment in the House (simple majority), with trial and removal in the Senate (2/3 vote), which we also all know ain't gonna happen.
