Pollsters Probably Didn’t Talk To Enough White Voters Without College Degrees

… With Clinton’s lead in the popular vote still expanding, the national polls are going to wind up having been pretty good (they showed her winning by 3 to 4 percentage points, and she’ll eventually win by about 2 points). The state polls? Not so hot. What matters, though, is not only the magnitude of the error in the state polls but the direction of it. The errors were correlated from state to state, and Clinton underperformed in a trio of states in the Rust Belt — Michigan, Wisconsin and Pennsylvania — that were supposed to have been part of her firewall; that underperformance cost her the Electoral College.

So, are these two things connected? Did Trump beat his polls in states with large numbers of white voters without college degrees?

The short answer is “yes.” CONT.
