This is a dangerous bluff. There is no way on gawd's green earth Rupert Murdoch didn't have the article describing the birthday letter screened by their attorneys with a fine tooth comb. All this will do is force the issue to the point that all Epstein information will have to be released, exposing many people in, shall we say, an unflattering light?
What this has done to the MAGA base is caused severe cognative dissonance - the state of discomfort felt when two or more modes of thought contradict each other. MAGA was promised for nearly 10 years that the Epstein cabal would finally be revealed, only to find they've been lied to. This was a primary foundation that 47 ran on and now MAGA loyalists feel betrayed. Numerous videos out there showing them burning their red hats out of anger.
The good news - there is hope for the MAGA loyalists who are finally realizing 47's superpower has been the ability to lie and get away with it, and are finally fed up with it. There is a group for redemption, and I hope people who are sick and tired of the treachery take advantage of it. https://leavingmaga.org/
