User:DukeOfDelTaco/sandbox/Statewide opinion polling for the 2016 United States presidential election

This article is a collection of statewide polls for the 2016 United States presidential election. The polls listed here provide early data on opinion polling between the Democratic candidate, the Republican candidate, the Libertarian candidate, and the Green candidate. Prior to the parties' conventions, presumptive candidates were included in the polls. State polling is not conducted in all states for the election due to various factors. More polls usually are conducted in states that are considered swing states as more attention is given to the results. For determining a statistical tie, the margin of error provided by the polling source is applied to the result for each candidate.
