One Wisconsin poll says Bush leads, another says Kerry

A couple of observations here. The first thing that stood out about these polls is the size of the samples used in both of them. The Badger poll had a sample size of 511 while the St. Norbert poll had a sample size of 402. As anyone who took a statistics class can attest, you need a sample size of at least 1000 to get within the 3% margin of error. These sample sizes will only get you to roughly a 6% margin of error. Therefore, I'd take them with a grain of salt.
