From Ballot Access News:
On March 11, the Arizona Senate Government Committee passed HB 2608 by a vote of 4-3. It makes it substantially more difficult for members of small qualified parties to get on their own party’s primary ballot. All Republicans voted “yes” and all Democrats voted “no”. The bill has already passed the House, and that was also a party-line vote.

Think of the GOP controlled committee as a Democratic primary for mayor in Chicago. We all know what the official out come will be come the proper election.
Correct me, if I’m wrong, but my understanding is that it requires a majority vote of the WHOLE
Senate. The vote of the “Committee” only determines whether the bill will be heard & voted on by the WHOLE Senate.
