We have to remember that we aren't all working from the same perceptual or moral framework. This is a struggle for me, as I love my parents but our believes have diverged considerably.
I think the challenge right now in the U.S. is that for many, it doesn't feel socially safe to question your own side. In reality, we need to feel free to judge actions individually, and judge leaders as a true accumulation of their actions. If we fear rejection from our party/family/friends for not walking in lock-step with the official party stances, that influences a lot of our thinking. No one wants to feel continually guilty about their own views (especially when there are social consequences for changing them), so we often shove aside conflicting details, make jokes, and signal to others that we're still a part of the tribe.
It sucks.
The knee jerk reaction is to run your party’s candidates and platform to the opposite extreme. Instead you should move towards the center. I really hope the democrats realize this (some do and are speaking out) soon.
You need to hold your political leaders responsible with your vote. Don’t just automatically vote for the politicians that are “saying” the right things. Find out what your representatives are “doing” and hold them responsible for their actions or more importantly, inactions.
That way they could vote in Republican primaries. Many if not most of those districts actually have Republican candidates in the primaries who are center right but they lose because primary turnout is very low, largely consisting of just the most extreme voters.
For example consider Marjorie Taylor Green (MTG). In the primary the first time she ran against a perfectly normal Republican. I don't remember all the details, but I believe he was a decorated military officer who after the military was a successful businessman and who had server in state offices.
MTG was a full on QAnon and other conspiracy theorist believer. But it is mostly the fringe that votes in primaries so she won. And it is a heavily Republican district with many people who don't really follow politics so she got their vote in the general election because they always vote R.
Register as a Republican if you are in such a district and vote in the primaries and then maybe we can get back to having sane Republicans winning those districts.
For safe Republican districts where they do elect sane Republicans, it is still worth switching registration. Let the current representative from that district know that you are doing this, and promise that if Trump gets upset at their vote on something and bankrolls a primary challenge, you will vote for them in the primary.
Also these voters are dumb but they aren't that dumb. Unless you know a person who actually has presented as a Trump supporting republican for the last decade and is secretly willing to switch sides after the election, you're not going to trick them.
The point is that center right Republicans (the kind that used to win most Republican districts before 2012) could still win if they could make it to the general election. They often can't because most Republican voters, like most Democrat voters, aren't into party politics enough to bother voting in the primaries.
It is the voters who are most likely to be to be farthest from the center who vote in the primaries, and these are the ones who don't want a normal center right representative.
If Democrats switched parties and voted in the primaries they might be able to counter the usual extreme primary voters so a center right Republican could win.
Congress is too beholden and scared of Trump on the GOP side to do anything meaningful. The democrats are generally spineless.
The federalist society and GOP have created a severe ideological imbalance on the supreme court that will have serious ramifications for years to come unless there's a serious effort to pack or reform the institution.
