Alaska lets candidates file for primaries very early. Already two candidates have paid the filing fee and completed the paperwork to be listed on the August 20, 2024 primary ballot for U.S. House. See them listed here on the Alaska Elections Division’s website.
One of the two early filers is Richard Grayson, whose ballot label will be “No Labels.” He is almost certainly the first candidate in any state who has already qualified to be on a 2024 ballot using that label. In Alaska, there are no party nominees, except presidential electors in the general election, so it would not be accurate to say that Grayson is the No Labels nominee. Grayson will not appear on the November 2024 ballot for U.S. House in Alaska unless he places in the top four in August.
