Polls over the past month have consistently shown a very close general election race between President Obama and Mitt Romney. The Rasmussen Reports daily Presidential Tracking Poll has shown Obama’s support between 44% and 46% every day for weeks. During that same time frame, Romney’s support has stayed between 44% and 47%.

While some of those voters could ultimately change their minds, the winner could very well be determined by the eight percent (8%) to 10% of voters who routinely refuse to commit to either of the major party candidates. About half of them prefer a third-party option, and the other half are simply undecided.

The survey of 653 Uncommitted Likely Voters was conducted July 2-15, 2012 by Rasmussen Reports. The margin of sampling error is +/- 4 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC. See methodology.
