The diverging standings of Stephanie Herseth Sandlin and Michele Bachmann are a pretty good prism into the political landscape right now.
John McCain won both of their districts by 8 points.
They both voted against the health care bill.
They both have opponents with name recognition well under 50%.
They have almost identical approval spreads- +12 for Bachmann, +11 for Herseth Sandlin
But Bachmann leads her likely general election opponent by 18 points and Herseth Sandlin only leads hers by 7.
Tough time to be a Democrat.
