Context: Trump's lawyers are in front of the Supreme Court arguing that presidents cannot be prosecuted for any crimes they commit while in office.
Who knows how the Calvinball refs will decide this one, but if they go Trump's way, Biden has literally no excuse not to assassinate his political rivals.
Dems don't want to win.
Not as their first priority at least.
They want
moneyfunding.Winning too much would hurt their bottom lines, both because being "the resistance" every so often brings in more donations and because listening to the public over monied interests would alienate them from those monied interests, and their donations.
This is also why they didn't definitively nullify the Comstock act or codify Roe v Wade when they had the chance. Because actually solving the problem means they can't campaign, and fundraise, on perennially preventing the problem.
Edit: forgot to actually get to the point lol, Biden would never, ahem, definitively, stop, Trump, because he doesn't have any reason to. He would then get a new opponent it would be harder to use the threat of to fundraise.
Trump is a fantastic heel for them and the Dem establishment would never actually stop stop him because it would then slow down the donations.
