“It’s my intention to run for lieutenant governor,” Martin said outside the Senate chamber. “We’re quite well organized and starting to get the word out.”

Martin, 56, has been in the Virginia Senate since a special election in 1994, and served in the House of Delegates before that. He works in financial services.

He joins an already crowded Republican field for the 2013 race.

Del. L. Scott Lingamfelter of Prince William is running, as is Corey A. Stewart , chairman of the Prince William County Board of Supervisors. Pete Snyder, chairman of the GOP’s VA Victory 2012, the Republicans’ coordinated campaign, reportedly also is considering a bid.

On the Democrats’ side, Aneesh Chopra, the former White House chief technology officer, is widely expected to run.

Other Democrats being mentioned as candidates for lieutenant governor are: former House minority leader Ward L. Armstrong (Martinsville), Del. Kenneth Cooper Alexander (Norfolk) and former delegate Paula Miller of Hampton Roads.

Bolling, the incumbent, is not seeking reelection because he is running for governor in 2013. He faces Attorney General Ken Cuccinelli II and White House party crasher Tareq Salahi for the GOP nomination.

On the Democratic side, Terry McAuliffe, a businessman and former Democratic National Committee chairman, plans a second run for governor, but he has said he will not officially announce his plans until after November’s elections.
