Moran, left, and Wolf are both retiring at the end of this session.
Looking forward, Democrats have to hope Kaine gets another job to create an opening.
In 2008, Obama considered Kaine as a potential vice presidential running mate before choosing Joseph R. Biden Jr. for the ticket. Democrats say Kaine could appear as a 2016 vice presidential candidate, or be selected for a Cabinet position if Democrats keep the White House in 2016.
In that case, Democrats listed a number of candidates who could run to try and succeed Kaine in the Senate. They include:
Lt. Gov. Ralph Northam, who was elected to that office in 2013.
Attorney General Mark Herring, who defeated Obenshain by a few hundred votes in 2013.
Anne Holton, who serves as Virginia’s secretary of Education under Democratic Gov. Terry McAuliffe. Holton is Kaine’s wife and also the daughter of former Gov. Linwood Holton, a Republican.
Vice President Joe Biden waits to conduct a mock swearing-in ceremony with Sen. Brian Schatz, D-Hawaii, in the Capitol's Old Senate Chamber, December 2, 2014. Schatz was sworn in to serve the remainder of his term since he was appointed to the seat after Sen. Daniel Inouye, D-Hawaii, passed away.
