Which party claims to be all about individual responsibility and law and order? Perhaps the conservatives’ embrace of post modernist nihilism has consequences beyond themselves?

I could just as easily ask you which party claims to be about justice, fairness and democracy?

Let's not mince words, politicians of all stripes are largely opportunistic and self-serving, and that's what the evidence is suggesting. There is not as much difference between either side on that point.

Ok, what would one party have to do to prove they are better than the other?

Define "better". Do you mean, "the clearly preferable option in any election", or "acting on issues most citizens care about", or perhaps even just "more trustworthy"? Because these are all different and they don't all break in the Democrats' favour in every election.

The abortion issue is a perfect example. They talked a big game for decades about codifying Roe, and did absolutely nothing every time they got into power, and just cynically used that as a lever in any election to pressure people into into electing them through scare tactics. Is that trustworthy? They seem to have gotten a boost in recent polls because of abortion, but oh boy if they don't follow through this time it will be a bloodbath in 2024, and rightly so.

Believe me, the Democrats are not above trying to subvert democracy to win either. They actually do it every election in a legal way, and recently tried to do it illegally and a judge smacked them down.

I get it, you hate the tactics both sides employ, but you at least agree with what the Democrats claim to stand for. Maybe ask yourself whether they actually stand for those principles or if that's just more cynical opportunism.
