The premise of this video is flawed ... You can't use a person's record as president to claim that they couldn't be elected today; because people wouldn't have that information about him when they were voting for him.
With that said, the world has changed a lot since the 1980s ...
Illegal immigration has become a dramatically worse problem (be sure to check the coloring scale)
Terrorists have become far more successful at striking targets in the western world, and the number of "attempted" terrorist strikes by individuals who have been radicalized on the internet is growing; and the economic base that suited the United States from the end of World War II to the 1990s has disappeared in favour of a consumption driven economy.
With how much the world has changed one would expect people's views of certain policies to have changed; especailly those policies which could be associated to the growth in the problems that are now facing the country and the world.
