You're giving excuses that make no sense. No one is saying to vote a straight party ticket. Do your research, take notes on the candidates, go vote. Why are you inventing this memorization nonsense?

You'll find that, while each candidate can have positions that you agree with and that you don't, but you probably have a pretty good idea which issues matter most to you, so you can focus on those issues. If they say things you agree with about things you care about, and they don't seem like liars, vote for them. You'll probably find one party's platform aligns with your preferences, and you only need to keep track of the ones not in that party if you really want to memorize the candidates. Or, find an organization you agree with and start from their recommendations.

But just bring your notes to vote, if you're allowed. My state is 100% mail-in voting, so I can fill out the ballot as I research. How many candidates are in your elections that is causing you to panic like this?
