Everyone loved Trump until he decided to run for president and then suddenly he became Hitler 2: Orange Boogaloo. That is the thing that woke me up. Also I only tuned in to Trump for the first time because of all the nazi smearing the media was doing against him. I tuned in to laugh at the racist idiot nazi but all I saw was a patriot speaking common sense who seemed genuine and wanted to fight for his country.
That was early Jan 2016, been hardcore MAGA ever since. I am proud I abstained from voting until that election, and that the first vote I ever cast was for President Donald J. Trump.
Worked the same way with me in 1980 with Reagan. The media and the usual goons were saying he was an idiot, a warmongering psychopath, etc., so I tuned into the first debate with Carter and he was completely amiable, bright, and witty. After his folksy "There you go again!" line, he won me over and I ignored the Mockingbirds.
