“What is ‘post-math,’ supposed to mean?”
I could be wrong, but think it was meant as a compliment to Mitchell and dig at Nate Silver.
I take “math” in this context to mean the reality of the 2016 election.
Pre-math (pre-election), Nate Silver was seen by many as the premiere election forecast prophet. Post-math (post election), not so much.
Interesting! Thanks for explaining that.
