Title: 2013 Virginia lieutenant gubernatorial election
Content:  The 2013 Virginia lieutenant gubernatorial election took place on November 5, 2013, to elect the Lieutenant Governor of Virginia. The incumbent Lieutenant Governor, Republican Bill Bolling, had originally planned to run for Governor of Virginia in the 2013 gubernatorial election, but withdrew upon the entry of Attorney General Ken Cuccinelli. On May 18, 2013, a Republican state convention in Richmond nominated minister and conservative activist E.W. Jackson over six others after four ballots. The Democratic primary on June 11, 2013 was won by State Senator Ralph Northam, who defeated Aneesh Chopra, former Chief Technology Officer of the United States. Northam then defeated Jackson by a wide margin in the general election. As the Senate of Virginia was evenly split between 20 Democrats and 20 Republicans, the lieutenant gubernatorial election effectively decided which party had control of that chamber.
