Yeah I'm not buying that Trump supporters are disappointed Obama voters, given that Trump was one of the main promoters of the 'birther' conspiracy theory.
I am more than willing to understand the Trump movement and think I do understand it better than most. I took issue with the lack of consistency in your comments above.
If that was what you meant in the first place then maybe should have written it as such. I see little evidence for your claim.
My view of the most recent election is that Trump did not attract a lot of marginal voter support (if anything, he had less than in 2020) but that Harris failed to attract any at all because she didn't define her policies well, didn't communicate well, and spent too much time chasing non-Trump Republicans while ignoring everyone to the left of that.
