Yes. It shows just how divided the country and what a huge difference (to how the country is run) a relatively small percentage swing in votes can make. And it's certainly not a "mandate" for all the MAGA-style changes that will now be attempted.
The problem is, and it's not new by any means, that whatever is done roughly half the country will disagree. It's easy to say "compromise" but our system is not really set up to facilitate that, though individual politicians can try of course.
It may be that this divide is the major problem our country faces. And I say that in the face of many other contenders for the "worst problem" award. If we could agree on what the facts are and then discuss what should be done, we would be a long way down the road to addressing these other matters. It puzzles me, frankly. To pick an example, everyone, even billionaires, will be affected by climate change, so logically everyone should be concerned with averting it.
