About this Poll Potomac completed a total of 1,200 telephone interviews statewide, July 6 – July 10, 2006, among a random sampling of likely-voting Maryland registered voters.

According to customary statistical standards, the statewide sample produces a margin of error of no more than ± 2.8% at a 95% confidence level. This means that, 95 percent of the time, the “true” figure would fall within this range if every likely voter in the state had been interviewed.

For smaller subgroups of the overall sample, the potential sampling error is larger. For example, the sub-sample of 604 likely Democratic primary voters has a potential margin of sampling error of ± 4.1%.
