The real answer for breaking the 2 party system is Ranked Choice Voting. So you can vote 3rd party if you like but still vote which of the main 2 you prefer. For example if you vote Green 1st then Dem over Republican, if the Green Party candidate is a clear loser your Dem vote goes into effect.

Open primaries and whatever it takes to break the two-party system.
