On June 1, Nevada SB 421 failed to pass the Assembly. It was repeatedly delayed, because the bill’s supporters knew it would lose if they did bring it up. See this Politico story, which says that most political observers Rand Paul will do better in a caucus than in a primary. Also see this Frontloading HQ story, which says that the bill might have passed anyway except that U.S. Senator Harry Reid used his influence to persuade Democrats in the Assembly to oppose the bill.
