Actually what I can foresee happening is the MAGA crew actually moving further Right, embracing the hardcore ideals of people like me and forming their own party. They might even be able to draw in some of the other small, right-wing parties.Because it's reality. Magaturds aren't going to be invited to join anything. They will be derided and can live on their fringe, under rocks and twist in the wind.
This would leave the RINO and Never-Trump types to live under a center-left banner, possibly pulling in some of the more centrist Democrats and leaving the Progressives on their own at the left end of the spectrum.
At that point you have a three party situation where presidential elections are going to become even more of a shit show than they are now.
