Trump’s legions are 75% of the Republican electorate, somewhere north of 35% of the total electorate. Thus the entire Republican Party is stuck with him. And because of gerrymandering and voter supression backed by very sophisticated AI psycological profiling and corresponding exploitation of human psychology Trump forces have us all trapped.
The only way that logjam can be broken is if the Republican leadership decides that saving the nation by joining with Democrats against Trump is more important than party power. Most likely by the time Paul Ryan, Mitch McConnell and other key Republicans get to that point it will likely be too late.
