China has spent far more. So yes it's a combination of trying to subsidize US production more in combination with tarrifs to make sure a domestic electric car industry can get off the ground too. Many countries in Europe are also making similar moves.
I don't know if it's really about "good guys" or "bad guys," it's about many countries, China included, wanting their own domestic production lines for cars.
If anything I would think government subsidies would be a preferable solution for people who had issues with the tarrifs. I would take this to be good news.
The reasoning was that in the old style of filibuster no other senate business was possible. In theory was supposed to help the senate be more productive. In practice, it's made the filibuster even more powerful. If a party was holding up all legislation and other functions of the senate by grandstanding for something stupid, that could hurt them politically, especially if it got bad enough that the military was being impacted or there were government shutdowns. So maybe they would think twice if it was worth a filibuster. Now they can kind of do it risk free. I think if you saw, government shutdown caused by Republicans trying to prevent abortion protections, well it'd be pretty unpopular with most Americans. And they'd pay for it in the polls. Or maybe not even do the filibuster in the first place.
