This is just too funny. According to CBS, the Romney campaign ended up buying fully into the "polls are skewed" junk science pushed by conservative bloggers.
According to the story, the Romney campaign "believed the public/media polls were skewed - they thought those polls oversampled Democrats." They "based their own internal polls on turnout levels more favorable to Romney" and used it to determine campaign strategy. Mitt Romney and Paul Ryan really believed they were winning - right up until election night.
That was a grave miscalculation, as they would see on election night.
Those assumptions drove their campaign strategy: their internal polling showed them leading in key states, so they decided to make a play for a broad victory: go to places like Pennsylvania while also playing it safe in the last two weeks.
In other words, the faulty analysis popularized by outsider "experts" like Jay Cost of the Weekly Standard, and Keith Backer of Battlegroundwatch.com became gospel within the Romney campaign itself.
Meanwhile Dean Chambers, who many credit or blame for starting the whole "skewed polls" craze, offered the following mea culpa yesterday:
UnSkewedPolls.com is just one web site and one project I did, and depending on your point of view it was proven wrong, it has run its course or it will fade away. It is merely a web site and only part of what I do and will do.
