In all fairness, Florida was not easy for anyone to poll this year, due to the hurricanes hitting predominately Republican areas.
Zogby was the joke of the year. He called the race for Kerry last spring, and then kept a consistent bias to the left all year. In an effort to make his final numbers correct, he announced that his final predictions would be released at 5:00 p.m. on election day. He later admitted that he used the early exit polls in making his final predictions, which was a joke on many levels. First of all, he is supposed to be a pollster himself. Why was he depending on exit polls? Secondly, within a few minutes of the earliest wave of exit polls being released, many on the net were crunching the numbers, and realizing they were seriously flawed. How on earth did he not notice this himself? Thirdly, even with his cheating by using early exit polls in his final "predictions" he still came up with one of the worst predictions. His career is over, which is why he's now going to do everything possible to try to make his numbers look better. He started the day after the election by using one of his earlier polls as his final prediction, which directly contradicted his Nov. 1 statement that his final numbers would come out at 5:00 on Nov. 2.
As for Zogby, his credibility started to crumble when he began polling for Tom Delay's opponent, Tim Riley (D), in the 2002 elections. Zogby has denied this, but the reason was that DeLay is a gung-ho Israel supporter, and, of course, Zogby is an Arab.
Yes, actually, I used the Nov.1 numbers from RealClearPolitics for Zogby; I thought I remembered his last-day numbers being even worse.
