To be honest, one thing that was so disappointing about the 2020 election (and now the 2024 election) is that it's shaping up to be one old white man against another old white man. Neither Biden nor Trump are representative of America, but I suspect that the Republicans know that Trump can't win due to his immense unpopularity among undecided voters. As a result, it looks like both the Democrats and the Republicans are waiting for the other to blink, although would the Democrats really oust a proven winner, especially one that won 12m more than the popular Obama?
IMO, if it does end up being Biden vs Trump Round 2, then I could see a billionaire like Bezos or Musk turning up and completely wrecking the field. Either of those two could tear the election apart, and both Biden/Trump would be sitting ducks against an insanely rich younger challenger with proven credentials.
