It occurs to me that they would be saying the exact opposite, had Trump won the pop vote, but hillary had won the electoral vote.
I suspect that the leftist “pundits” would become strict constitutionalists, had such an event occurred.
All their previous talk of “The Blue Wall” is all you need to know. They were hanging their hat on (again) winning the electoral votes, not necessarily the total votes, in at least PA, OH, and WI to add to The Blue Wall.
