I am pessimistic that he is "stuck". Billions and billions and billions of dollars are rarely stuck. The demographics are changing, but not nearly enough so that a D win is inevitable. That, paired with some of the structural victories he already has achieved (redistricting, conservative supreme court) make me believe that we are going to see his legacy continue for decades on. Dark.
Murdoch doesn't care that he created a monster, he only cares that he can't control it. He wants to replace it with a monster that he can control even if that monster turns out to be worse than Trump.
This is really poor journalism. This narrative of Fox creating Trump is bogus. In the 2015 Republican primaries Trump began as an outsider. All the big money was on the anointed Jeb Bush, who Fox largely supported. After Bush was eliminated then it was Ted Cruz getting the red carpet. Actually Sean Hannity was one Fox presenter who kind of rebelled and gave a voice to Trump.
Only when Trump had prevailed over Cruz did Murdoch bend the knee. Murdoch has been a political parasite for decades in Australia and Britain. He doesn't create anything really, but just backs whoever is convenient for his own benefit and kingmaker ego. Trump created his own grass roots movement and had to fight his way up through the Republican political establishment, as did Bernie Sanders with the Democrats who unlike Trump could not overcome the nefarious bullshit thrown at him.
Fox didn’t create Trump in the same way you don’t create the plants in your garden. Murdoch created Fox to shift the national discourse toward rage and fear, which was the perfect environment for Trump to flourish. They may have set out to grow one plant, but another seed took and they cultivated it aggressively once it did.
