I think the US will always be divided now.

The seed of that started with Reagan getting rid of the Fairness Doctrine in 1987. That gave rise to hate radio, seeping into the rural areas where radio is a prevailing companion on long empty roads.I drove across the US on holiday a few years ago, and it's appalling what's on local radio over there. Try to get a weather report/traffic report and get a healthy dose of right wing propaganda. Couple that with all the dodgy religious programming and an alternate universe is created. And then came Fox News....

It's a cultural civil war over there, and it's going to be around for decades to come. It's like two countries in one now, and if Biden gets elected, he'll get nothing done. Mitch McConnell has already said he'll BLOCK any Biden liberal cabinet heads.

Good article about this by a Professor of History at Columbia University:
Trump has not been repudiated – a Biden presidency would face obstruction at every level
