Reversal of fortune for pollsters

Back in 2000, Zogby was the man. He was the only major pollster who got the national vote percentages correct and his calls on all the major battleground states were dead on. Rasmussen, a highly respected pollster in his own right had a tough time in 2000. He had Bush with about a 6 point lead going into election day. As we all know that never materialized.

Fast forward to 2004. Someone learned from their mistakes and someone made some new ones. Zogby was off. Way off in some cases but Rasmussen was more accurate in almost every instance, dead on in some cases. But often I saw around the web, Rasmussen being discounted as partisan because of 2000 and because he appeared often on Fox. Here's a comparison between he and Rasmussen's polls for the 2004 election:

Arizona

Zogby had it +6% for Bush

Rasmussen had it +5 for Bush

Final +11% for Bush

Arkansas

Zogby had it +3% for Bush

Rasmussen had it +7 for Bush

Final +9% for Bush

Colorado

Zogby had it too close to call

Rasmussen had it +5 for Bush

Final +7% for Bush

Florida

Zogby had it +.1% for Kerry and trending Kerry

Rasmussen had it +5 for Bush

Final +5% for Bush

Zogby had it +5% for Kerry

Summary: On straight state calls, regardless of margin Rasmussen went 19-0-1 on these 20 battleground and possible "poachable" states. I gave him a tie on Minnesota because he had it tied and it went for Kerry.

Zogby, on straight state calls didn't fare as well. He went 14-3-3. He had the call wrong on Iowa, New Mexico, and Florida. You'll notice that he had all of these called for Kerry and they went for Bush. He did not have any predicted for Bush that went for Kerry.

Margin Predictions: The real difference comes when you examine the margins each predicted. Rasmussen was closer to the actual result than Zogby in 16 of the 20 states above. Zogby was closer in only three and in one, they were off by the same margin.

Of these 20 states, Rasmussen nailed the margin on four states: Florida, Michigan, Pennsylvania, and Wisconsin. And he was within 1 point of the actual margin in five states: Iowa, N. Carolina, Washington, New Hampshire, and Nevada. He was within 2 points on five others: Virginia, Ohio, Oregon, Colorado, and Arkansas. That means Rasmussen was within 2 points in 14 of the 20 states. Talk about accuracy. His worst performances were in West Virginia and Tennessee, where he was off by 8 points in each respectively. The average difference between what Rasmussen called for these states and actual was 2.25 points.

Zogby on the other hand nailed only one: Ohio. He wasn't within 1 point on any others. He also wasn't within 2 points on any others. Out of 20 states, Zogby was only within 2 points is one state. That's abyssmal. His worst performances, points wise came in Tennessee, West Virginia, and North Carolina. He was off by 10 points in each of them. But one could argue that his calls on Iowa and Florida were even worse. He was off by 5 points or more in both AND Kerry leading in both. He was off by more than 5 points in Virginia (8), Iowa (6), Colorado (7), and Arkansas (6). The average difference in what Zogby called and the actuals was 5.15 points.
