In a first-past-the-post voting system with winner-take-all representation, it’s literally impossible for a 3rd party to be elected to the presidency. If you’re really committed to changing that, you’d vote for the people who are more likely to enact ranked choice voting and proportional representation (regardless of party)… and only at the local/state level since that’s where voting laws and regulations are made. Voting 3rd party for president does nothing but dilute the vote of the intended opposition party. Greens dilute the Dem vote, Libertarians (both big and small) dilute the Republican vote. To pretend otherwise plays right into the game the two big parties have always played.
