Harford County Executive David Craig has been a Havre de Grace city councilman, its mayor, a member of the Maryland House of Delegates, and a state senator. And he’s one of four Republicans vying for his party’s nomination in next week’s gubernatorial primary. Among his top, would-be priorities: An elimination of the state’s personal income tax. He’d also slash government spending. His push: To make the state more economically competitive. Other goals include an elimination of the so-called “rain tax,” and a roll back of environmental regulations. Guest host Nathan Sterner
