The East Valley Tribune, which covers the eastern Phoenix suburbs, has this article about HB 2305, an election law bill sitting on the Governor’s desk which makes it very difficult for members of small qualified parties to get on their own party primary ballots. The reporter quotes several Republican legislators as saying that they wrote the bill that way because they are upset that Libertarian candidates last year were on the general election ballot in certain races. Such quotations are likely to be relevant to any lawsuit against the measure, if the Governor signs it into law.
Similar remarks were made earlier this year by Montana legislators, when they passed a top-two measure and arranged for the voters to vote on it in 2014. Montana Republican legislators openly said they are tired of having Libertarians on the ballot.
