I'll be the first to admit, as a researcher myself, I'm a fan of statistical methods for explaining and predicting the phenomenon we see in the real world.
But with the lousy polling in 2012, mostly showing a Mitt Romney edge at the end, coupled with the abysmal projections of a Hillary Clinton blowout in the Electoral College in 2016 -- polling is now as useful as voodoo to predict politics.
Why is this?
