Wow. What dem talking point website gave you that idea? You don't know how polls work? They can be national or state by state. NATIONAL polls might find a pop vote lead. But you now have a HARD DEMONSTRATION of someone cherry picking an inconsequential factoid out of the air.
What MATTERS is the state by state polls. And -- if you WANTED TO -- you could do a meta study and COMBINE THOSE to get national numbers. UNFORTUNATELY --- most of the state by state polls were ALSO very whacked in the head. Here's the Cliff note.
ANYONE forecasting winning percentage from a NATIONAL set of numbers is spinning you..
BECAUSE -- it was INDEPENDENTS that determined the election. And the OLD polling methods of weighting Dems and Reps predictably failed to produce accurate forecast. In FACT, the OLD method of polling is shot. Antiquated. Worn-Out. Useless anymore. Because the number of rabid partisans is rapidly falling.
The new methods use "extreme vetting"..

Not joking. It's true. Polling companies collect PEOPLE. Get to actually know them. And pull representative samples from (as Romney says) binders full of voters. This MAY restore the accuracy. It's yet to mature..
