About this Poll

Mason-Dixon Polling and Research Inc. of Washington, D.C., interviewed 625 randomly chosen registered Idaho voters on Wednesday through Friday (Oct. 20-22), limiting the interviews to people who said they are likely to vote in November. The statewide poll’s margin of error is 4 percentage points, with a 95 percent probability that results would fall within that margin if the entire population were sampled.

Sixty additional interviews were conducted in the 1st Congressional District to bring the total sample size there to 400 likely voters, and 15 additional interviews were conducted in the 2nd Congressional District to bring the sample size there to 300. The margins of error are 5 percent in the 1st District and 6 percent in the 2nd. The extra interviews covered only the congressional races.
