In my state, getting at least 2% of the vote for either Governor or President in a general election keeps the Party on the ballot for the next election.
Without hitting that 2% threshold, the party loses its official status and has to go back to petitioning status, which means resources are tied up both canvassing for tens of thousands of signatures and fighting in courts to get reinstated. So it’s a perpetual ground game and prevents the party from taking off.
The Libertarian Party has remained above that threshold for about a decade now, the only third party to do so consistently, and that’s pretty scary.
+1 Singapore. Good food, I don’t stand out in a crowd, future city.
