Florida has several ballot-qualified parties that have not nominated anyone for President. It had been thought plausible that either the Independent Party, or the Independence Party, might nominate him for President. But the Florida Secretary of State’s office said neither of those parties nominated anyone for President.
This Politico story says that in the states in which McMullin is on the ballot, it is now too late for him to replace his stand-in vice-presidential nominee with his actual vice-presidential nominee. The stand-in, Nathan Johnson, never wanted to actually run for vice-president. The reporter, Daniel Strauss, was unaware that there is case law from Florida, Pennsylvania, Indiana, Virginia, South Dakota, and Alaska which says independent presidential candidates (or independent candidates for Governor) have a right to replace their stand-in vice-presidential or lieutenant governor running mates with an actual candidate later. In 1980, John Anderson was permitted to replace his stand-in for vice-president, Milton Eisenhower, with former Wisconsin Governor Patrick Lucey, even though Lucey wasn’t chosen until August 27, 1980. Lucey’s name was on all ballots except South Dakota’s.
