*some of the powerful interestsPowerful interests that control the U.S. government want Trump.
If this was about protecting US from another Trump term, they would have told Biden to step aside.
Otherwise the Biden faction wouldn't (all but frame) Trump with criminal charges. Pro-Biden oligarchs have more dirty methods they can use.
While Trump is supported by the extreme nationalist faction, this faction has always been weaker than the "traditional" oligarchs, which espouse nationalism under the cover of neoliberalism, as opposed to religious nationalism.
The traditional US leader faction has never been as weak as today, thanks to exhausting their economy, losing their full control over media, and Biden himself falling apart at the seams. But they're still the strongest interest clique in America, and it wouldn't surprise me if they went as far as outright using Trump as a patsy to clear their opposition.
Gather all the "anti establishment" votes into Trump, then drop a bomb on him (Biden faction still controls the courts, establishment can even stick a pedophilia charge on Trump). Only issue is that Biden probably can't function as a puppet for 4 more years without falling apart.
We are seeing a power struggle unfold.
