The Nevada Senate Committee on Legislative Operations and Elections will hear SB 499 on April 1 at 3:30 p.m. The bill title says it sets up a “modified blanket primary.” It would provide that for all partisan office except President, all candidates would run in the primary. Only the top two could run in the general election, except that if the top two candidates in the primary are both in the same party, then the 2nd place finisher does not advance to the general election, and whichever candidate who is not in that same party does advance (however, if all the candidates are members of the same party, then the top two would advance).
Although this sounds somewhat like a top-two primary, the bill consistently uses the term “party nominee”. Top-two systems are not constitutional unless the ballot warns voters that there are no party nominees, and SB 499 not only uses the term “nominee”, nowhere does it provide that the ballot should carry language explaining that there are no party nominees.
Blanket primaries are unconstitutional if any party subject to them complains. The U.S. Supreme Court invalidated involuntary blanket primaries in 2000 in California Democratic Party v Jones. The principle behind that decision is that parties can’t be forced to let members of other parties help choose their nominees.
The sponsor of SB 499 is the entire Senate Committee, so it seems likely that the Committee will pass the bill. However, observers do not believe it would pass the Assembly even if it passes the Senate.
