Matt chats with Gehrke, the Trib’s newly minted columnist, his new gig after years spent as a reporter covering the Utah Legislature, as well as writing about politics in D.C. They discuss what Gehrke has learned about how the Legislature works after years of close observation, from the role that Gov. Herbert plays, to which legislators are most powerful, to how lobbyists wield influence, to why positive environmental and clean air legislation sometimes struggles to pass.
