If there were enough libertarians in the state to elect libertarian legislators, this wouldn't be an issue.
Instead of whining about how the government (sense the irony here) isn't helping Libertarians stay on the ballot, why don't the libertarians run some grass (pun intended) roots campaigning to boost their numbers in the state.
But then again, when all you do is smoke pot, it is hard to get motivated to do much more than reach for the bag of doritos.
If an election were required to put the name of every nutcase group that rose out of the muck on the ballot, the ballots would be books.
I don't, however, see anything wrong with requiring all candidates to come up with 75,000 signatures to get on the ballot. Require it of one, then require it of all.
Beyond that, the ballot should always have a write in section. If you can't get the signatures to get your name on the ballot, then there's still hope.
