I would say forming a new party is probably the best move, but ultimately getting another party that isn't red, blue, or yellow (sorta) on every ballot in the country is incredibly difficult, as in the laws are specifically designed to discourage it from happening. The Green Party, for example, only appeared on 37 of the 51 state ballots (DC Included.)
It's actually kinda insane that our national election doesn't have a nationally standardized ballot.
I mean to their credit they made it way farther into the judicial process than we ever did with Trump.
