      This state does not have enough data to show polling averages. Averages will not be displayed unless a state has at least five total polls or polls from at least three pollsters.

      Our average includes all candidates that FiveThirtyEight considers “major.” Candidates with insufficient polling data are not displayed in the averages. State polling averages are adjusted based on national trends, which means candidates’ averages can shift even in the absence of fresh state polls. Read more about the methodology.
