Trying to build viable third parties by voting for them in presidential elections is like trying to build a third door in your house by repeatedly walking into the wall where you want the door to be.
Want to build a viable third party for presidential elections? Start small at the city/county level and eventually you will have candidates at the state/federal level. Today's city council is tomorrow's senator/president. Does it really surprise anyone that a relatively unknown and unproven candidate outside of the two major parties doesn't get any traction in a federal election?
we aint getting elected viable third party until the two party regime is denied legitimacy which is done by not voting for either party. deny them engagement by voting third party, anyone really.
If you are talking about viable third party candidate, then my position is: current political stage has no room for one hence why i shill more a narrower scope goal of "deny the two-party regime legitimacy"
Something that people can get behind, act upon individually and directly while avoiding getting sucked into political left/right circle jerk.
Bigger picture would obviously involve a proper 3 third party candidates to upset the duopoly. Either by winning outright or forcing the two parties to provide concessions to the voters instead of current "get fucked peasants, I am serving my corpo daddies"
These 3p candidates need for voting public set the stage for them by making third vote a viable path for a politician/movement.
My original thesis enables this while not getting into the political weeds but it does not stop others from building on it. If people got their 3p, then they should shill it! Even if every person votes for their own guy but sufficient amount of people do it, then it would still lead to awkward situation why are there 9% of voters who did not chose "regime"
