Fox News has this story about the attempt to qualify the No Labels Party for 2024 ballots, for the purpose of placing a centrist presidential candidate on the ballot. The most interesting news in the story is that No Labels says it would nominate a presidential candidate by convention in the first three months of 2024.
No Labels is very similar to Americans Elect and its 2012 efforts, but Americans Elect used an on-line presidential primary for its process. Ultimately Americans Elect did not run anyone for president in 2012, and it asked states to eliminate it from the ballot. Nevertheless, there were a few candidates for non-presidential public office who ran under the Americans Elect label in 2012 and 2014.
