The fact of the matter is that Bernero can't campaign to save his life.
With just one exception (1990 GOP John Engler), Michigan has been like Virginia (since 1977) and New Jersey (since 1989): Since 1978, the state has been electing to the governor's mansion the opposition White House party [candidate]. If that trend holds, Republican Rick Snyder has the advantage to win the general and become the 48th governor of Michigan.
As for Democratic gubernatorial nominee Virg Bernero: For someone who "can't campaign to save his life," he's been effective at getting elected to the Michigan Senate and Michigan House of Representatives, prior to winning election in 2005 as mayor of the state's capitol, Lansing.
But don't let these facts get in your way.…

There's a Difference between Campaigning and winning a General election in Lansing and winning statewide. Let me ask, when was the last time he had a remotely competitive election? According to Wikipedia, Lansing's last Mayor election wasn't even contested by the Republican party.
