Can someone please give me a logical reason why any American liberal should have hope?

I consider myself very liberal, I have voted in every major election since I was 18, I have volunteered, and I have worked for two congressmen. I don’t think I’ll ever vote again or donate, and I think I’m going to follow politics less/look at Reddit less. Even if the Democrats win in 2028, Trump is going to replace Thomas and Alito with 35 year old 4chan mods and the Supreme Court will be extremely conservative for at least the next 40 years. This means nothing significant will happen for the next 40 years. If the Democrats ever get the votes they had when they passed the ACA again then that program will get struck down just like they did with Biden’s student-loan forgiveness program.

This goes to a fundamental problem. Most Democratic ideas are expensive, take time, and are hard to implement. Republican ideas are simple and are mostly just cutting things/destroying Democratic ideas. I think the Democrats have better ideas, but in our system they can’t successfully implement most of them while the Republicans can at least save you some money or make life harder for some other people you don’t like.

I have never in my life since such a rejection of liberal ideas and such failure by the Democratic party. Our ideas are less popular now, many very blue areas are not desirable places to live anymore, we lost every swing state, Trump had more overall votes, New Jersey is a swing state now, the Republicans control every branch of government now, and the Democrats lost Hispanic men/had major losses with almost every demographic. The Democratic Party failed. They should have prosecuted Trump immediately, they should have never allowed Biden to run for reelection/they should have been promoting an heir apparent, and they should have had actual fair primaries instead of just appointing Clinton, Biden, and Harris. For most of my life Republicans were the hall monitors who told people what to do and how to think, but lately the Democrats are like an HR department or nagging spouse telling people how to act and think while the Republicans have somehow become the counterculture/antiestablishment more populist party. The Democratic Party is stuck defending a system that most people think is corrupt and does not work for them.

Where do we go from here? What can be done? I really do think it is over and life for most people will never be better than it is right now.
