Statement of Methodology:

The statewide tracking survey of 500 likely New Hampshire Republican primary voters consists of a two-day rolling average and includes only those respondents who indicated that they were very or somewhat likely to vote in the January 23, 2024 New Hampshire Republican Presidential Primary. The field was conducted January 21-22, 2024, and is based on live telephone interviews. Each area’s quota and demographic information -- including geography, gender, and age -- were determined from the 2020 Census and exit polling from like elections. Samples of both standard landline (11 percent) and cell phones (89 percent) were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each county were proportionate to the number of likely voters expected based on similar open Republican primaries in past elections. New Hampshire’s 10 counties were grouped into four general regions. Respondents in the household were selected by initially asking for the youngest adult. The margin of sampling error for results based on the total sample is plus or minus 4.4 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document that follows. All surveys may be subject to other sources of error, including but not limited to coverage error and measurement error.

This survey of 1,000 New Hampshire voters was conducted between January 3 and January 7, 2024, and is based on live telephone interviews of adults who indicated they were planning to vote in the General Election for president in November of 2024. Each area’s quota and demographic information were determined from 2020 Census data and exit polling from like elections. Samples of both standard landline (11 percent) and cell phones (89 percent) were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each county were proportional to the number of likely voters expected based on past elections. New Hampshire’s 10 counties were grouped into four general regions. Respondents in the household were selected by initially asking for the youngest adult. The margin of sampling error for results based on the total sample of 1,000 is plus or minus 3.1 percentage points. The margin of error for the subset of 318 respondents who indicated they are likely to vote in the New Hampshire Democratic primary is +/- 5.5 percentage points; the margin of error for the subset of 491 respondents who indicated they are likely to vote in the New Hampshire Republican primary is +/- 4.4 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document that follows. All surveys may be subject to other sources of error, including but not limited to coverage error and measurement error.
