About this Poll

This poll was conducted by Mason-Dixon Polling & Research, Inc. of Washington, D.C. from April 5 through April 7, 2010. A total of 625 registered Nevada voters were interviewed statewide by telephone. All stated they vote regularly in state elections.

Those interviewed were selected by the random variation of the last four digits of telephone numbers. A cross-section of exchanges was utilized in order to ensure an accurate reflection of the state. Quotas were assigned to reflect voter turn-out by county.

The margin for error, according to standards customarily used by statisticians, is no more than plus or minus 4 percentage points. This means that there is a 95 percent probability that the "true" figure would fall within that range if the entire population were sampled. The margin for error is higher for any subgroup, such as a gender or regional grouping.

This poll also includes two over-samplings - one of likely statewide Republican primary voters and one of likely general election voters in the Third Congressional District. These over-samplings are additional voters added to the statewide survey in order to increase the sample size within the two sub-groups and these respondents were only asked the questions relative to that section of the survey. The margin for error on both groups is plus or minus 6 percent.
