An eternity ago, right after the election, Brian Riedl and Sean Trende made an important observation: the election polls were so far off that all public polling must be garbage.
I don't care *that much* on how horse race polls are off (except that perhaps it forced a misallocation of resources), but a skew in public opinion polling is potentially a big deal. https://t.co/PVFBWGyQwL

Politicians rely on public polling for many of their decisions (right or wrong), and polls influence judges and bureaucrats also. If polls can't remotely predict the highest-profile election ever, why should we have any confidence that anything they say is accurate? This goes way beyond politics.
