Remember the SurveyUSA chart I posted a few weeks ago?  They conducted another poll of possible presidential/vice presidential tickets in four states:  Iowa, California, Minnesota, and Wisconsin.  Open Left has compiled both rounds for a few states to compare/contrast.  Here are the results:

As you can see, in all four of these “test” states Edwards is the only candidate that sustains and improves Obama’s campaign.  I agree with Paul Rosenberg from Open Left:  Of course name recognition (and lack thereof) limits the accuracy of these polls, they still mean something.  People are comfortable with what Edwards has to offer Obama and the country.  In a campaign that is apparently going to be focusing on the economy, Edwards is a great candidate to add, especially for Obama to continue to make some headway in the Appalachian demographic.

Let me know what you think.
