7 Day Congressional Ballot Jul-Aug

At Rasmussen Reports we interview 1,000 Likely Voters every single night. Data on this page reflects a seven-day rolling average sample of 7,000 Likely Voters spread equally over the preceding seven nights. Our surveys were of 500 Likely Voters each night prior to September 1, 2004.

This seven-day sample reduces the random variation that can come from smaller sample sizes and polling on different days of the week.

The seven-day rolling average is useful in cutting through the statistical noise of smaller samples and measuring the overall flow of the campaign. However, it lags behind other indicators in measuring reaction to breaking news. Seven-day rolling average data is also available for the Presidential Ballot and the President's Job Approval Ratings. Three-day rolling average information is also available for the Generic Congressional Ballot, the President's Job Approval, and the Presidential Race.
