Third parties will never happen in first past the post elections. 2 parties will have enough of the general platforms to get 51% and 49% of the every single time. And if you’re a voter who can think rationally, you’ll vote for the big party that’s close enough rather than throw your vote away on a 3rd party vote.
If there are any flash in the pan third parties, their platform will get absorbed by the big 2 and it’ll disappear.
A third party is fundamentally irrelevant in the design of our democracy. This poll should be 0% support.
