There's more than two parties. Nobody is forcing you to vote for one of them. Parties are also an anti-pattern. Again we need a better system than first past the post that naturally biases towards a two party system.
Due to practicality and congressional gridlock, this has to happen state by state, and in many states the 'easiest' method is some sort of ballot initiative. I encourage anyone who reads this to look up the process in their state (https://ballotpedia.org/List_of_ballot_measures_by_state) and at least try to get a signature out to one so they show up on the ballot.
