I believe donald trump will not run for president as a republican. desantis or someone else will be the republican candidate instead... however I believe donald trump WILL run for president as a 3rd party candidate.
donald trump is the only person alive right now who even has the slightest chance of winning as a 3rd party candidate. and if a 3rd party candidate wins the election, people could finally realize they don't HAVE to vote for the lesser of two evils anymore. it would be a chance to do away with the awful 2 party system we have now.
of course, all of this is just a prediction, and it likely will not happen this exact way, but it was a thought I had recently and figured I'd share it all with you and see what you all think.
John Andersen ran third party in 1980 after he lost the republican nomination.
