Hard to run in 2024 from another Country. POTUS Trump is not retiring from the fray because of jackals nipping at his heels. He is in it for the long haul.
I myself think he will get in briefly, and for some reason will not catch on. 2024 is a long way away, he is not going to be as sprite and on top of his game as nine years earlier when he started, and likely Melania will not be on the team as well. It is just based on history of presidential races, and the fact that so many want him to fail so they can take up that banner, but they have to put a sweet face on it, and hold it in and avoid all criticism of him. He is not particularly loved by a good segment of Capitol Hill; they just have to go along due to fear of him and his base. It is not built upon for example the way Reagan constructed his base of loyalty where the guy engendered true, deep love and uplifting inspiration. I lived through those days. Big difference from this current situation.
