RACINE, Wis. — House Speaker Paul Ryan didn’t act like a man facing a nationally watched primary, spending Monday making typical district visits to local businesses while his upstart opponent furiously campaigned across Wisconsin’s First Congressional District hoping to make history.

Ryan talked taxes and manufacturing and of course, cheese, at A&E Hand Tools and at Ocenco Inc. The first company is a maker of automotive diagnostic tools while the second produces safety equipment for factory workers and lighting systems down the road in the small town Pleasant Prairie. He answered employees’ questions about how the federal government can make their companies more competitive and whether he supports the Trans-Pacific Partnership.
