There will never be another Reagan. A Trump in his 1980s was sharper, more diplomatic and well spoken. That Trump today, then a Democrat, would win in a landslide.
However, hopefully there are Reaganites. Rubio seems to be one to a great degree, especially in regards to National Security. He happens to be the one politician I listen to and respect in this regard.
Trump is also very much like Reagan, even despised by the same Establishment that despised Reagan. He uses the same motto, the same song, the same "peace through strength". He also happened to be at his peak at the same time Reagan was in his during the 80s. His outreach to working class voters and non-whites, something they even had an acronym for when Reagan used his outreach. They also both work very hard. Reagan ran circles around Carter in his first election in terms of stamina and activities.
Clinton was more of a Reaganite than 99% of politicians today let's not forget.
Trump attacked Reagan in the 1980s.
