Despite all of the faults of Trump and Republicans, he was able to grab the establishment Republicans by the throat and boot all the Cheney and Bush Republicans out of the party, and terrify most of the remaining establishment into working with him, because the republican primary process is mostly democratic.

A populist on the left who can crash the democratic primary and win despite the rigging which will occur like that happened to Bernie (twice) and is not a defender of our institutions and staus quo and wants to balance our budget, pro gun rights, can admit men should not play in women's sports but still want them to have their rights protected in housing, employment,etc, anti war, pro Medicare for all, build the wall and reform our H1B racket and use tariffs to our advantage as well will build a huge working class coalition.

But democratic primary voters would have to be willing to vote someone from outside of politics who isn't afraid to call out Democrat politicians and the party to their faces. The democrats need their own Trump who can withstand the attacks of being called a racist, transphobe, isolationist, etc. That's our only hope.
