Hate

Hate is powerful and it works. The allure of Trump was that he said the quiet parts out loud and for uneducated voters tired of a system rigged against them, he was their mouthpiece. Never mind what he actually did or didn't do.

Biden may not be the best president the US has ever had and yet he is quietly getting things done such as putting the economy on the right track and getting infrastructure projects going that will ultimately help the country. So while progressives don't like him for his history as a neoliberal centrist, the right despises him because he is doing things to help people. Meanwhile the GOP flails and continues its culture wars for lack of any public policies other than cutting taxes for the wealthy which is why they need to distract from any points Biden is scoring with the electorate.

Hate has been the primary selling feature of Trumpism and it has coalesced all of the malcontents into one movement which will do absolutely nothing for the country other than sink it. No better spokesman then in having someone who spews it as readily as they breathe.
