She has stated emphatically that she WILL NOT run as a third party candidate.......which means it’ll more than likely happen.
An attempt by so-called centrists to set up a "No Labels" Presidential candidate could be done with someone like Joe Manchin or Kristen Sinema, or possibly Mitt Romney or another RINO who stayed out of the primaries. However, we are near the end of February. The only two parties that have near 50 state ballot access are the Green and Libertarian Parties, and neither party would accept someone seen as a big corporation (Green) or statist (Libertarian) candidate. Therefore, a "No Labels" party would have to go through the process of getting on the ballot. As RFK, Jr., has found out, it is an arduous and expensive task, and more difficult now than it was for Ross Perot in 1992 or George Wallace in 1968. Additionally, the Democrats would engage in lawfare against a "No Labels" party. Such a party would appeal to the mushy middle of suburban women and country club Republicans that are needed by the Democrats to flip to Biden (or Michelle Obama or Gavin Newsom).
