Different reasons and different issues.
I think we're on the wrong track on a number of issues. I suspect you do too. But do we agree on those issues? And, maybe even more important, can we agree on how to address them?
Just to take one example that I care a lot about, Trump and the Rs want to drill more and roll back emission controls. Trump and Biden both want to make it hard for ordinary people to buy inexpensive Chinese electric vehicles. Those are terrible values, imo. To the extent possible, fossil energy deposits should stay in the ground and we should be aggressively switching to greener sources, greener businesses, greener homes, greener vehicles, etc.
