(CNN) - Rep. Bart Stupak of Michigan says he's staying put rather than make a bid for the Democratic nomination for governor.
Stupak, a 9-term congressman who represents Michigan's upper peninsula and much of the northern part of the lower peninsula, says he'll instead run for re-election.
"I believe I can best serve the people of Michigan in the U.S. Congress. My seniority and experience in Congress, where I sit on the Energy and Commerce Committee and serve as Chairman of the Oversight and Investigations subcommittee, afford me a significant opportunity to affect positive change," said Stupak in a statement Tuesday morning.
Stupak also spoke to the timing and costs of running for governor, saying "it is difficult for me to commit to pursuing a state-wide gubernatorial campaign at this critical time. The compressed time frame and fundraising requirements necessary to secure the Democratic nomination for governor would be very difficult for me to achieve without sacrificing some of my responsibilities in Washington, DC."
Stupak's announcement comes just a couple of weeks after Lt. Gov. John Cherry, a fellow Democrat, withdrew his name from the race. Democratic Gov. Jennifer Granholm is term limited and prevented for running for re-election.
With the state unemployment currently at 14.3 percent and the seat open, Republicans see Michigan as a good opportunity to grab back a Democratic-held governorship.
