Governor Approval Rankings Q4 2018 Methodology

Morning Consult conducted 416,841 surveys with registered U.S. voters from Oct. 1 through Dec. 31, 2018, to determine the Q4 2018 Governor Approval Rankings.

In each poll, Americans indicated whether they approve or disapprove of the job performance of their U.S. governors. For each question, they could answer strongly approve, somewhat approve, somewhat disapprove, strongly disapprove, or don’t know / no opinion.

Morning Consult obtained an up-to-date list of governors from Sunlight Foundation’s Congress API v3 and Open States API. Survey respondents were assigned to their appropriate governors based on their state of residence.

Morning Consult obtained population parameters for registered voters from the November 2012 Current Population Survey. We applied post-stratification weights at the state level based on gender, age, educational attainment and race.
