it's kind of a bizarre feedback loop, but the reason why there won't be a viable party outside of two party system is the same reason people still vote for establishment.
the fear of the unknown and clinging to status quo too much. certain candidates running just for strategic vote handling is kinda tiring
not even related to this primary, really. just overall. run everyone for primary and let popular vote decide

this eliminates all these fukkery of voltron, party structure people wielding power, etc. put all people who actually wanna run, you got one chance to vote and everyone's on the same page
same reason why electoral college should be abolished
