One-term Republican incumbent Senator Norm Coleman continues to keep lead DFL challenger Al Franken at bay, according to the latest poll of 615 registered (not likely) voters by SurveyUSA.

The poll, conducted April 30—May 1, gives Coleman a 52 to 42 percent advantage, well outside the survey’s margin of error. Coleman also led Franken by 10 points in SurveyUSA’s March poll, 51 to 41 percent. Coleman has never trailed Franken in the six polls SurveyUSA has released dating back 15 months to February 2007.

The new poll also has Coleman up by a 55 to 36 percent margin over DFL hopeful Jack Nelson-Pallmeyer and 53 to 35 percent over DFL-er Darryl Stanton.
