Changing from electoral votes to popular votes wouldn't really make much of a difference. It would just make much more sense, be less confusing, and make our country look less stupid.
Roosevelt, jfk, clinton, reagan, etc would have still won the presidency. Bush would have lost (would have been nice not to go to war with iraq... maybe 911 never happens and the middle east isn't as bad and maybe there are less terrorist organizations out there and less terrorist attacks) and trump would have lost. (I think in a few years we will all wish he would have lost)
Seems like the country would be better off if we went with the popular vote.
