Unfortunately, the blog post of May 16, saying that the Missouri legislature had passed SB 797, was mistaken. The bill had passed the Senate, and then on May 14 had passed the House, but the House had added something new to the bill, so it needed to be passed by the Senate again.
On May 16, the Senate concurred in the amendments, so it appeared that the bill had passed entirely. But in Missouri, that wasn’t enough; the Senate not only had to concur in the addition, but it had to pass the bill again as a separate action. Although the bill had no opposition, the legislature went home without doing that final action. Thanks to Barbara Woodruff for pointing out the original error. The bill would have corrected the typographical error in the law that was passed in 1993. Generally a group is free to circulate a petition for recognition in Missouri before it has chosen its nominees. But the glitch means that if the group wants to run a presidential candidate, it must list the presidential candidate on the petition. Fortunately the Secretary of State permits a stand-in presidential candidate, who can be changed later.
