The intelligent thing to do is to vote for the major party that is objectively better than the other major party, while volunteering to help any 3rd parties you have interest in so they slowly become more viable. If everyone did this, we'd be in better shape in the short run by electing the non-FelonRapistPedoTraitor party while making things better in the long run by elevating at least one 3rd party.
Cuz right now no 3rd party is even really trying to be viable. So it just isn't an option. People have to help them for that to happen.
