A Reddit comment by user “Damichia480” in the “Conservative” subreddit reads:
It too late he straight up broke every campaign promise.
“No new wars” Bombed iran and is about to fund Urkaine like Biden did
“Mass deportation” not enough and is keeping the illegal immigrants working as slaves and H1B
“I will release the Epstien files” “The flies on my desk” - Pam Bondi. Recanted everything he said and say there no flies and Republicans BLOCKED the release
Patel was hired to take care of the deep state but he is no different from them
“The Party told you to reject the evidence of your eyes and ears. It was their final, most essential command.”
RIP MAGA we been terribly lied to and betrayed by the people that shouldve served us but they devolved into being part of the establishment.
It was a long time ago I read that. This is the closest thing I could find, saying 6 in 10 Trump supporters proclaim they will never stop supporting him no matter what: https://www.cnn.com/2017/08/17/politics/trump-approvers-never-stop-approving-poll
Edit: on reflection, I may have done some rough estimating to get from 6 in 10 Trump supporters to about 25% of America overall.
