ROLL CALL: U.S. Chamber Backs Justin Amash Primary Opponent. “The U.S. Chamber of Commerce endorsed GOP Rep. Justin Amash’s primary challenger in Michigan’s 3rd District. The group’s support could translate into television airtime for Brian Ellis, a former East Grand Rapids School Trustee, before the Aug. 5 primary. The primary has become one of this cycle’s top battles inside the GOP, with the party’s libertarian wing backing Amash and national business interests boosting Ellis.”

So the Chamber’s priorities are noted.
