All of this has me wondering if there is some sort of system where politicians and billionaires are kept in line or installed, or even forced into positions of power once there is sufficient kompromat to make them do the needful?

Of course there is. Everyone who spent significant amount of time with Epstein is likely compromised. Trump, Clinton, Gates. It's highly unlikely it stops with Epstein though. There are likely all kinds of blackmail going on with US politicians by what amounts to a Jewish mafia. Lindsy Graham certainly acts like the Israelis have shit on him. Probably child porn or something worse. There's no logical explanation for his unhinged hatred of anyone and everyone who opposes global Jewry and Israel. I mean he recently called for Putin, the leader of a country with the largest nuclear arsenal on earth to be assasinated for christ sakes. Graham acts like someone desperate not to have compromising information released.

Really though, every US politician is blackmailed by global Jewry and the Israeli lobby through their money, media, lobbying power, and thorough infiltration of the national and domestic security and legal apparatus. To not enthusiastically support them in their agenda is to bring down all of these on you and end your political career. Who in congress or the federal government actually opposes any of this? I cant think of anyone aside from Tulsi Gabbard to some extent. Maybe Madison Crawford a little bit. The rest are all bootlickers unless you count Ilhan Omar and Rashida Tlaib, who support it on everything except Israel, and the J's seem to be carefully and methodically working to remove them if possible, and isolate them if it's not(they could do it regardless but it would come at a potential cost unless they can astroturf sufficient opposition by their sacred POC golems in order to mask that it's Jews that want them gone.)
