About this Poll

The head-to-head results for the U.S. Senate race poll amount to 99 percent because of rounding.

The Journal Poll is based on a scientific, statewide sample of 606 voters who voted in the 2010 general election and said they were likely to vote again this year.

The poll was conducted Aug. 12-14. The full voter sample has a margin of error of plus or minus 4 percentage points. The margin of error grows for subsamples.

Research & Polling Inc. generated a stratified random sample in which each New Mexico county received a representative proportion based on turnout patterns in the 2010 general election for governor.

When necessary, RPI weights the surveys to reflect the known distribution of age, gender and party affiliation, based on the 2010 election. Racial and ethnic proportions are based on RPI estimates of turnout patterns.

All interviews were conducted by live, professional interviewers, with multiple callbacks to households that did not initially answer the phone.

Both landlines (70 percent) and cellphone numbers (30 percent) of proven general election voters were used.

Voters who reported they are unlikely to vote in the coming election were screened out.
