This second Trump win turns MAGA into a movement bigger than Trump himself. The first win was Trump catching the establishment and the electorate off guard, it was one of the closest post war elections alongside Kennedy/Nixon, Bush/Al Gore.
If Trump had died after his first term, MAGA would have died with him but this second win is so comprehensive, it suggest MAGA has tapped into something deep in the American psyche. If he dies in his second term he will become a martyr and MAGA will be even stronger. Evangelicals think he was sent from God.
