All Republicans have to do at The More That You Read The More Things You Will Know The More That You Lean shirt is select someone a little younger who’s slightly less stupid than Trump and who doesn’t shove his foot in his mouth every 5 seconds, and they can beat Biden simply by not being either Trump or Biden. Their base will be unified in their hatred of the opposition far more than they will care about who they have to support. This establishes the new norm within the party as being farther right than the cycles before Trump. At that point, what path to change do you see progressives having? They can’t primary Biden effectively without giving things to a unified Republican party. If Biden wins another term, as he might given the power of an incumbency, Republicans will have every reason to win the next time, as our country simply doesn’t stay consistent when it comes to your guy having been in power for 8 years. Elections -tend- to go to the opposition in those cases.
