I love voting third party, mostly because my state is super blue and I can do so. If you’re left in a super red state, then you really only have one option. This means that if you want to change the dichotomy a critical mass of third party voting needs to be achieved, which is becoming harder and harder.
So in this case, focusing on what you think is right - which might be something that has no representation - leads to lower voter turnout, or people splitting the vote. I believe this is a huge factor in Trump’s second victory.
Maybe you might have a bigger chance to force a change inside a party, but currently only the Dems do have something that resemble a political party.
Voters have no say in GOP, even the GOP leadership themself doesn't have anymore. Last election there was a large out-walk, overtake is now complete. Just a few people behind the MAGA facade call the shots atm.
