Since 2002, the Suffolk University Political Research Center has been successfully polling and analyzing elections and political issues right in Suffolk's backyard. In elections for Senate, Governor and President, SUPRC has been in the field in the Bay State for over ten years.
Statement of Methodology
This survey of 600 registered Massachusetts voters was conducted between June 5 and June 9, 2019, and is based on live telephone interviews. Each area’s quota and demographic information -- including race and age -- was determined from 2010 Census data. Samples of both standard landlines and cell phones 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 similar past elections. The 14 Massachusetts 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 +/- 4.0 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.
