About this Poll

This poll was conducted by Mason-Dixon Polling & Research, Inc. of Washington, D.C. from September 13 through September 15, 2010. A total of 625 registered Idaho voters were interviewed statewide by telephone. All indicated they were likely to vote in the November general election.

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 party grouping.

For the state’s two congressional races, an additional 60 interviews were conducted in the First Congressional District in order to bring the total sample size there to 400 likely voters and an additional 15 interviews were conducted in the Second Congressional District to bring the total sample size there to 300 likely voters. The margin for error in the First District poll is +/-5% and it is +/-6% in the Second District poll.

These 75 additional voters were only asked the questions relative to their congressional race and are not part of the statewide poll of 625 voters.
