First off no poll is perfect. Ever heard of margin of error?
They had Sink up by 1, What did Scott win by again?
Also how long before election day was the poll conducted?
They only had Romney winning by nine in the FL primary, but it was a few days earlier then the several polls done right at the end that caught the full extent of Romney's momentum there were thus closer. They also got the Hispanic numbers correct.
Seriously people, chill out about every damn little point in poll and enjoy the ride.
