I don't know how they unskewed the polls of the major networks... I wish there was more on their method.
Even as a big Mitt Romney supporter, I think the results of those unskewed polls are too far in Romney's favor.
However, I think the larger point to be made is that all of the polls from the mainstream media outlets are skewed in favor of the Democratic Party, given the higher number of polled Democrats, despite the national majority of conservative voters. That doesn't accurately reflect the views of the voting populace.
These are links from your source where two Democratic pollers admit that their polls are skewed towards the Democrats...
Is the latest Washington Post/ABC poll skewed for Obama? - Arlington Conservative | Examiner.com
Commentary: The mainstream media polls are skewed for a reason - Arlington Conservative | Examiner.com
That's the major point of the issue... Not to trust any of the polls released by major media networks... whose agenda places their polls several points to the left...
Honestly... I think the real status of the election is somewhere between what Gallup and Rasmussen have, +/- 2-3 pts... which is about a dead heat, with Obama maybe having a slight lead, because of recent polls in swing states...
This is still going to come down to the debates, any potential october surprises, and turnout on voting day...
