Former Virginia Governor Mark Warner says he won't run for president in 2008 because a national campaign would require him to spend too much time away from his family.

The Democrat met with reporters in Richmond today and said he arrived at his decision over several weeks. He said neither his wife, Lisa Collis, nor his daughters discouraged him from running. His daughters are ages 12, 15 and 16. Warner said it's the right time "to have a life for a little while." Warner said he won't rule out running for Senate or his old office again.

Republican Senator John Warner's seat is up for election in 2008 and the next governor's race is in 2009. But he would not commit to seeking either job. Warner also did not rule out a future presidential bid, but he added that, "Things will probably never be as aligned as they are right now." Since Warner left the governor's office in January, he has busily toured key states in the Democratic nomination process, particularly New Hampshire and Iowa.

His political action committee, Alexandria-based Forward Together, has raised money for Warner's exploratory effort and for other Democratic candidates in this year's midterm elections.
