Seriously great question at this point. In 2016 it was commonly accepted knowledge that if Putin released a video of Trump getting pissed on by a woman in a Moscow hotel, that would be the end of his political career.
Since then, he’s been found to be a rapist in court, has attempted to overthrow the government, and has been found guilty of about 3 dozen felonies with more charges pending - which doesn’t matter any way since Trump’s judges have granted him legal immunity to anything he wants to do. And he was just convincingly reelected with his party winning both the House and Senate.
At the point, Putin could put out a video of him personally pegging Trump, and it would make no difference.
I dunno. The human part of me wants to believe that there would be something that would be to much for his base to stomach. But the pessimist in me that’s still processing last week’s election makes me think there could be a video of Trump and Epstein raping a 13 year old and his base wouldn’t give a shit.
