Dude, reality has provided these two candidates. One is the sitting president, who always runs. If you have a problem with how we get our candidates, I probably agree with you, but we've already run that gauntlet for 2024. The time to change that process is before the general, not AT the general.
We have two viable candidates. One will destroy the country. The other will frustrate us with how little they do to improve it. NO OTHER candidate who shows up to replace Biden is going to change that description. It's going to literally be the same two sentences. If you are going to vote in a way that helps Trump get in, at least have the honesty to recognize that's what you are doing. You aren't going to change shit for the better, you are just going to make it a faster slide into things getting worse. You will help Trump and his supporters while literally changing 0 things for the better.
