Consider: In 1980, there were 18 states where the presidential margin was at least 5 points more Democratic than the national result, 18 states where it was at least 5 points more Republican than the national result and 14 states in between. Hypothetically, over three successive election cycles, all either party needed to do to win a Senate majority was win all 36 of the seats in the friendly states plus at least 15 of the 28 swing-state seats.
Today, Republicans don’t even need to win any “swing states” to win a Senate majority: 52 seats are in states where the 2016 presidential margin was at least 5 percentage points more Republican than the national outcome. By contrast, there are just 28 seats in states where the margin was at least 5 points more Democratic, and only 20 seats in swing states.
