because it's what they want to believe.
Trump was close friends with Epstein, Epstein's own brother called Trump Epstein's wing man. They hung our for a long time and Epstein found some of his victims at Trump's home/club Mar-A-Lago. Jeff Epstein donated the use of his plane to Clinton's charity, they barely knew each other, but the meme has the press only talking about Clinton and Epstein. No one is asking Trump to answer for his relationship with Epstein.
Can you imagine if the videos of Epstein and Trump were of Epstein and Clinton? Or if Epstein would have found victims at the Clinton's private club? There's a lot of evidence suggesting Trump and Epstein were close friends for many years. And Trump was accused of rape by a minor at Epstein's apartment. All of that is getting ignored and Bill Clinton's loose relationship with Epstein is all they're talking about.
... obviously not the same as me. Then they probably really hate the Clinton's. They probably believe Clinton Cards (a Hallmark cards type store chain in the UK) is owned by Bill and Hillary (it's not).
And the comments from those bots further galvanize the right-wing voters.
