Why on earth would one of the most high profile, most well-respected polling companies in the nation sit out the last week of what is arguably one of the most important elections in recent US history?
Makes absolutely no sense, and neither does his making any predictions about the eventual outcome of this race, given the above.
Unlike others, I have no theory as to why he sat out the last week in Massachusetts. My only point is that he's now damaged his reputation as a pollster for coming out with this curious (and unsubstantiated) call on the election outcome.
As polling accuracy gets better, at some point polling reports will be equivalent to calling the election before it is over -- and that is exactly what infuriated Republicans when the networks called Florida in 2000 before Florida's western Panhandle polls closed an hour later than eastern Florida.
At some point, increased polling accuracy could predict elections before they happen. When that becomes possible, should polling companies voluntarily restrain from polling in the last few days before an election?
