Governor Granholm's campaign has turned in nominating petitions, a day before the filing deadline for the August primary ballot.
About 40 Granholm campaign volunteers gathered outside the state Bureau of Elections this afternoon with over 35,000 signatures, more than double the number needed.
Granholm did not attend because she is on a trade trip in Japan.
The governor is not expected to have an opponent in the August Democratic primary. She likely will face Republican businessman Dick DeVos in November.
