Seymour is pointing out how irrelevant to popular vote is, Trump didn't try to win the popular vote, he totally ignored the two largest states which always go democratic anyhow.
The democrats can win all the biggest cities by a total of 20 millions votes, they're not winning the electoral college without some appeal to middle america
My football analogy, the game is not won by the team that moves the ball at will between the 20's and settles for FG's, it's won by the team that scores TD's in the redzone
It's NOT about yardage, it's about scoring, and it's never going away
