Sacramento City Councilman Kevin McCarty has announced he's taking another shot at a state Assembly seat. McCarty, a Democrat, is hoping to replace Assemblyman Roger Dickinson. Dickinson has formed a campaign committee to run for the state Senate when President Pro Tem Darrell Steinberg is termed out next year. All three are from Sacramento. This is McCarty's second try. He lost a close Assembly race to Dickinson in 2010.
