Rasmussen's outfit at the time, Portrait of America, had Bush beating Gore, the day before the election, by 9 points... I believe he had it at 49% - 40%
It might have been without the cheating.
Rasmussen SEVERELY underestimated the number of cigarettes and liquor miniatures that would be handed out by Democrats on Election Day in 2000.
I hadn't focused on the POA -- Rasmussen connection. Very interesting. He bombs out one year, and changes names.
That's very reminiscent of the strategy of football prognosticators. Pick up any pre-season college football or NFL magazine (Street and Smith's, for example), and you'll see page after page of advertisements for betting services which will, for a stiff fee, provide you the names of "sure winners" for each week of the upcoming season. And most of these services (Vegas Hotline, or Coach's Guaranteed Picks, or Pigskin Pro, to make up a few names) will brag about their track records from previous seasons. But of course, those with low success ratios don't take out ads (at least not under the same name) the next year.
