The Democratic congressional race in California's 47th district is intensifying. State Sen. David Min and litigator Joanna Weiss have been feuding publicly through ads. Min accuses Weiss of using campaign money from sex offenders, while Weiss criticizes Min for a DUI. Both campaigns claim the other candidate is a liability for the party, increasing the risk of primary weakness. The Orange County seat is a toss-up, with both candidates facing potential challenges in the general election from Scott Baugh, a former Republican lawmaker.
