I STRONGLY believe there is a slew of politicians, mostly Republican (reasons coming), who are not only on the list but possibly also recorded in the acts. This is used as blackmail to control the corrupt congressmen. I say Republican because Trump used to be a Democrat, and was probably in league with Epstein to gather this dirt. Now he's using it to his advantage.
Another source of dirt was Trump's years of close ties to the National Enquirer, a rag that printed gossip and outrageous stories ("an alien from Zeta Eridani was my maid" type nonsense). That data was handed over to Trump during his first term.
As for Democrats - it seems either there are far fewer that are thus under Trump's blackmail control, or... they are totally ineffectual at thwarting Trump's rise to dictatorship because they are threatened with exposure if they properly resist.
