ALEXANDRIA, Va. – A liberal “family values” PAC is targeting Republican state Delegate Bob Marshall’s campaign for Congress — while staying mum about the presumptive GOP front-runner.

Virginia Family Values PAC was launched in 2005 with the goal of “defeating key legislators who promoted the intrusion of government power into the private decisions of couples and families in such matters as contraception and private sexual relations.”

Marshall, the most outspoken social conservative in the General Assembly, is in a crowded race to fill Northern Virginia’s 10th Congressional District seat held by retiring Republican Rep. Frank Wolf.
