"How accurate was Strategic Vision in 04?"
My recollection is that it was pretty good in state polls, although not as good as Mason-Dixon. Does anybody have stats on the 2004 polling companies?
Might as well stick with apples-to-apples, since a polling company might in theory be better in one state than they are in another. President Bush won Florida by 5 points. The last SV poll, finished on October 31, showed the President with a 4 point lead. Their two previous ones showed another 4 point lead on Oct. 27th and a 2 point lead on the 24th.
Given the margin of error on the polls, and given that even their last one had 4% undecided, that's about as close to perfect as you can get.
Strategic Vision did really well in Florida. Rasmussen also nailed it, getting the 5 point final margin on the nose with his 10/27 release (his last of the year for the state).
And just looking up one other state for the hell of it, the last SV poll for Georgia showed a 14 point Bush lead. He won by 17.
