Even in the face of Trump’s humiliating defeat at the hands of an opponent they believe to be weak and suffering from dementia, Republicans and conservative commentators continue to enable the human embodiment of what they once decried.
They do it because their crusade stopped being about anything other than causing their opponents pain a long time ago. They came to the crossroads and struck a deal to make a human troll the president of the United States, because he put Obama in his (birth) place and made all the right people mad. He was their vehicle to give the finger to half of the country.
Their end of that deal paid off in spades the past four years. And as he petulantly refuses to concede defeat they continue to get the liberal schadenfreude they crave.
The only thing they had to do in order to get it, was become everything that they had claimed hate.
