It's not both sides-ism. I am saying that the Republicans can't guilt-trip their voters, so they aren't constantly moving to the left and having platforms that their voters hate, relying on their only appeal being lesser evilism. It is because the Democrats need to constantly move right for their donors, and can in some respects ignore the wishes of their base through the logic of "lesser evils" that Biden can continue building Trump's border wall, try to outflank Trump on the right on immigration, and continue to support genocide, when 4 years ago, liberals could understand these policies are fascist.
