"We further attempted to experiment with novel weights not used by other pollsters, such as weighing on social trust, socioeconomic attitudes, and religious attitudes as measured by the General Social Survey, correcting for polling's tendency to oversample atheists and people with high social trust. We also weighed by Facebook usage, correcting for polls tending to oversample online voters."
Not sure if this is genius or stupid. We'll see come January
It might not work, but I don't think it's stupid for them to try: we have to fix polling somehow, and until then we just have to throw ideas at the wall until something sticks.
