U.S. Representative Tim Walberg beat Douglas Radcliffe North in the 7th District GOP primary in southeastern Michigan.
The 63-year-old Walberg, of Tipton, defeated 61-year-old North of Jackson in Tuesday's primary.
Walberg was first elected to the House in 2006, but lost in 2008 to Democrat Mark Schauer. He then defeated Schauer, who is running for governor this year, in 2010 to get back the seat. Walberg won again in 2012. Walberg also was in the Michigan House from 1983 to 1999.
Walberg was considered a shoo-in for the primary. He now faces Democrat Pam Byrnes of Chelsea in the November election. The 67-year-old Byrnes has a law degree and served represented the 52nd District in the Michigan House from 2005 to 2011.
