“I have decided to seek re-election to continue to serve as your United States Representative for Michigan’s new 11th Congressional District; and, I am committed to promoting and implementing a platform of principled conservatism,” McCotter said in a statement.

“Truly, Michigan and America’s best days are ahead of us because of you.  Together we will transcend our challenges; revitalize our economy; defend our freedom; and bequeath our exceptional nation to our children.”

McCotter is a conservative who was first elected to Congress in 2002. His presidential bid gained little traction after entering the contest in July.
He failed to gain enough support to be included in Republican debates and finished last in a field of 11 Republicans in the Iowa straw poll in August.

McCotter has pushed for reforms to Social Security and a harder line with China during his campaign.
