State Sen. Hansen Clarke has jumped into the Michigan governor's race now that Lt. Gov. John Cherry has decided not to run.

The Detroit Democrat said Tuesday in a phone interview that he has filed the paperwork to kick off his campaign.

Clarke has been traveling statewide to promote his plan for cutting auto insurance rates by 20 percent and says he will campaign on lowering costs in many areas for struggling businesses and families.

Clarke served six years in the House before being elected twice to the Senate. A lawyer, he also ran unsuccessfully for mayor of Detroit. He's term-limited and cannot run again for the Senate. His term expires at the end of the year.
