The latest news on this front comes from a really interesting article at Ballot Access News written by the widely-respected election expert and advocate for third party/independent ballot access Richard Winger. Take a look at this excerpt:

On May 12, the Nevada State Senate Finance Committee passed SB 292. It moves the petition deadline from June to May for new parties, and also imposes a severe distribution requirement on that petition. Now the bill goes to the State Senate. All Democrats on the committee voted for the bill; all Republicans voted against it. The bill also creates a straight-ticket device.
