Very unclear how this will progress

While this sounds very bad:

 there are several likely complicating factors yet to unfold:

*  more "Trump in private" disclosures to come (making no difference to Trumpists, but still influential on establishment Republicans who don't want to see a return of Trump influence?)  

*  Trump's personal legal problems coming to a head in the next year 

*  possible international tensions coming to a head, and (hopefully) being capably handled by Biden (perhaps a bit of Chinese or North Korean military sabre rattling?)

*  some key right wing media figures having their own problems removing them from influence.  Alex Jones is now facing several defamation law suits which may well harm his career;  Rush Limbaugh will die one day.   On the other hand, Fox News though is going harder right to try to get back audience from OANN and Newsmax.   

 I think it is impossible to overemphasis the damaging role of Fox News and the rest of the RW media universe in restoring "normal" politics again in the US.
