LITTLE ROCK, Ark. (AP) — Running for a congressional seat in a red state that went for Donald Trump two years ago, Clarke Tucker talks often about his bout with cancer and the federal care health law that expanded coverage for those without insurance. "I beat cancer here and became one of the million Arkansans with a pre-existing condition," he says in one television ad, standing in front of a cancer institute in Little Rock. But Tucker doesn't talk much about being a Democrat, something that's a deal breaker for many voters in a state that hasn't sent one to the U.S.
