Walker opens up seven point lead among likely voters in final Marquette poll

A month ago, Wisconsin’s most respected pollster showed Walker at 50 percent and leading by nearly six percentage points. Two weeks ago, the race tightened considerably, with Democrat Mary Burke pulling into a tie with the incumbent — thanks in large measure to some puzzling shifts in the internals. Marquette Law School’s final poll of the race shows dramatic movement back toward Walker.

This could be the story of the election.
