As we've seen here and on many boards, the polls are over-weighted by democrats who like to mouth off their opinions, where republicans just go about their lives working and dealing with their families and other obligations. No big surprise.
To be fair, polls that show an outcome we like we tend to put in our “talking points”, polls that show an outcome we don’t like, we criticize...notwithstanding hidden (and not so hidden) agendas, ridiculous sampling and other methods used by pollsters to skew polls, it is what it is. A snapshot in time of the people surveyed at that time, with the sampling as set at that time.
