McCotter, the fifth-term congressman who signaled last week he was considering a Senate run, said he's stepping aside for other GOP hopefuls.
"I did not wish to be a distraction for the stellar candidates now stepping forward to consider seeking the GOP U.S. Senate nomination," McCotter, of Livonia, said in statement that did not mention specific candidates.
Representative McCotter is just one more Michigan Republican who has decided not to jump into the race. Former West Michigan Congressman Pete Hoekstra and former Michigan Secretary of State Terri Lynn Land have both announced recently that they wouldn’t seek the GOP nomination.
Only one Republican candidate has entered the race so far. Former Kent County Judge Randy Heckman announced he would run for the seat earlier this year.
Stabenow has held the U.S. Senate seat since 2000.
