Mark Warner

Democrat Mark Warner’s supporters will be the first to know whether he’s running for governor or for the Senate. The former governor will make his plans known in an e-mail Thursday to friends, donors and political and business associates. Monica Dixon, who heads Warner’s political action committee, Forward Together, said the announcement will be without pomp or fanfare so as not to overshadow this year’s legislative elections. Shortly after the announcement is made, Warner plans to fly to Hampton Roads for a Democratic legislative fundraising event. Friends and advisers to Warner say he’s likely to run for the U.S. Senate seat that Republican John Warner will vacate with his retirement after five terms next year.
