Nope, didn't miss a thing. He's switched parties three times in the past 26 years. He was no fan of Reagan, rumors to the contrary. And only eight years ago Trump had
effusive warm praise for Hillary and Bill Clinton, at the same time he officially endorsed McCain, then a little while later, switched parties to Republican. He apparently thought McCain was better than GWB. He also supported Romney. In fact, he pretty much "re-discovered" the Republican party right about the same time it was repelling a lot of conservatives.
Guess you missed that.
