This Courthouse News Service article about the hearing in Libertarian Party of Illinois v Scholz seems to suggest that the Libertarian Party will prevail, based on the comments and questions the judges expressed during the oral argument.
Arizona House Bill 2484 moves the primary from the 10th Tuesday before the general election to the 11th Tuesday. On February 20 it passed the House Rules Committee. If this bill had been in effect in 2016, the primary (for all office but president) would have been August 23, not August 30.
If the bill becomes law, the petition deadlines for newly-qualifying parties, and for non-presidential independent candidates, would become one week earlier.
On February 16, the Arizona House passed HB 2302 by a vote of 34-24. It says that any presidential elector who fails to vote for the presidential candidate who received the most votes in November is deemed to have resigned. It says the chair of that elector’s political party has the ability to replace that elector. The bill makes no provision for the possibility that an independent presidential candidate might conceivably carry Arizona. If the bill passes, one wonders if the state chair of the major political party that carries Arizona will be expected to sit in when the state’s electors vote, so that he or she would be available to choose another elector.
On February 23, South Dakota Governor Dennis Daugaard signed HB 1037. It lets independent candidates for President choose a stand-in vice-presidential running mate; it does the same for independent gubernatorial candidates, relative to Lieutenant Governor.
The bill also moves the petition to qualify a new party from March to July, but only for parties that are willing to forego running anyone in their first year on the ballot for Governor, Congress or state legislature. The Libertarian and Constitution Parties have a lawsuit pending in U.S. District Court. If it wins, new parties that submit petitions by July would be allowed to nominate for all office, not just some offices.
On February 23, the Arizona State Senate unanimously passed SB 1307, which moves the deadline for political parties to file the names of their presidential elector candidates from late May to late August.
