The only reason why Trump is even a contender is because of these two shitty parties and the Democratic leadership backing some of the worst candidates in existence. Every election is going to have people claiming the opponent “will lead to millions of deaths and destruction” because nothing is going to change which is why we had to vote against him in 2016, again in 2020, and now again in 2024. Even after he dies there will be another Trump popping out of the woodwork.
By continuing to support these two parties, you’re just ensuring this will continue until the sun burns out. Neither party has any reason to improve things because they’ll get your vote regardless of how awful they become. Even aiding in genocide isn’t enough to alter your decision.
