If the republic is destroyed, none of these can even be addressed. And I believe Biden’s opponent is intent on the destruction of our republic’s inherent systems.
There aren’t many concerns that are comparable to the evil of abortion, but the concern you raise here might be one of them. What is less clear is whether the threat comes from the right or the left.
One of the key features of our electoral system is the electoral college, and while (the generic) you might not appreciate it, eliminating it would fundamentally alter our entire system. If an election was based solely on a national total, the smaller states would be completely ignored. The city of Indianapolis has the same population as the state of North Dakota; Los Angeles has more people than Idaho, Montana, Wyoming, North and South Dakota combined. So: which party is trying to circumvent the electoral college?
The courts are the third branch of government, headed by the Supreme Court. Which party is thinking of adding more seats to that court specifically to overturn the existing justices, and placing justices who will hand down the desired political opinions?
The filibuster in the Senate has existed pretty much since our founding. It is a maddening rule in that it makes it amazingly difficult to pass legislation that is not supported by both parties, but it has provided a valuable balance to keep the country from swinging wildly from one path to another depending on election results. Which party is discussing eliminating the filibuster?
As for the Senate itself, there is now a reasonable balance between the two parties, so control of the Senate, like that of the House, switches parties every few elections. Which party is contemplating adding two more states for the sole purpose of giving themselves four more seats in the Senate and tilting that balance more strongly toward themselves?
I think I agree with you that some of our fundamental systems are being threatened, but we fundamentally differ on the source of that threat.
