Republican Congressman Justin Amash has beaten challenger Brian Ellis in the 3rd District primary in western Michigan.
The libertarian-leaning Amash was targeted by business groups as being too far outside the mainstream of his party. But Amash survived the challenge and is likely headed toward a third two-year term in the Republican-leaning seat that includes parts of five counties and the cities of Grand Rapids and Battle Creek.
Ellis is an investment adviser who loaned $1 million to his campaign and received support from national, state and local Chambers of Commerce.
Amash has made waves in Washington by bucking the GOP leadership. He is a favorite of grassroots and Tea Party activists.
Amash will face movie theater owner Bob Goodrich in November. Goodrich was unopposed in the Democratic primary.
