Virginia Lt. Gov. Bill Bolling will be alongside GOP presidential hopeful Mitt Romney Tuesday afternoon when Romney files petitions to get his name on the Virginia primary ballot.
Bolling, who is Romney's state chairman and hopes to succeed Gov. Bob McDonnell, endorsed Romney in August.
The other two Republican statewide officeholders -- McDonnell and Attorney General Ken Cuccinelli have not yet made endorsements.
Cuccinelli said he may eventually back someone in the Republican field. Sources said it's possible McDonnell will stay on the sidelines. His role as the president of the Republican Governor's Association means staying neutral would make sense. Another good reason: The fact that McDonnell is mentioned as a possible vice presidential running mate.
