The CNN Poll of Polls is an average of five Florida polls of likely voters conducted over the past week and a half: Quinnipiac University/CBS News/New York Times (Sept. 18-24); Mason Dixon (Sept. 17-19); Washington Post (Sept. 19-23); American Research Group (Sept. 20-22) and Fox News (Sept. 16-18). The Poll of Polls does not have a sampling error.
The CNN Polling Center displays data from polling organizations that use CNN-approved
polling methodology as well as some that do not. The asterisk symbol * indicates that
the poll or polling organization does not meet CNN's methodological standards.
A CNN Poll of Polls is calculated using at least three polls that use CNN-approved methodology.
The Congressional Ballot polling data was provided by PollingReport.com.
A fresh batch of polls in Ohio, Florida, Iowa and Nevada - which together account for 59 electoral votes - were released by the Washington Post and American Research Group and were all conducted over the past six days.
