Reposting one of my favorite Reddit comments here (worth every award that was given by other users):

The reason they hate Fetterman so much is because they want a conservative Fetterman. Big, strong guy who speaks his mind without caring what his detractors think about it. Taking the elitist Oz down with a simple insult like the crudité vs vegetable platter.

They hate AOC partially due to sexism and racism but you can also clearly see the jealousy as Boebert and the Blonde try to be the right-wing AOC.

They don't understand that AOC and Fetterman are effective because they are trying to do what is in the best interests of the people they represent. The people that support them are actually supporting them, not just doing it to own the fascists. The right is empty, they have no plan, no policy aside from what will piss of the libs so their base can feel like there is someone below them.
