I don’t put much stock in individual polls. I do put great stock in composites of different polls and sadly they were accurate.I was jumped all over on this board whenever I suggested the polls were a source of concern.
A lot of folks on here were quick to dismiss and quick to monkey with the numbers to try to show that no matter a poll said John McCain was really winning based on its numbers. “If you change how you weigh the young folks and reduce registered dems to this, etc, etc you get McCain by 4.”
538's composite was almost uncannily accurate:

The big surprise was IN, and Obama's margin there only around 25,000 votes.
