About this Poll
On the evening of October 15, we called 1,499 likely voters in Iowa (Margin of Error: ±2.6%), and 1,206 likely voters in Colorado (Margin of Error: ±2.9%) and asked them who they plan to vote for plus an array of demographic questions. We included Libertarian Gary Johnson to measure support for a third party. Each of the following results have been weighted to correct for any over-/under-sampling, and we’ve included the breakdown of self-described Republicans / Democrats / Independents that completed the questions.
