Independent candidates running for Congress had until June 12 to turn in the 1,000 signatures needed to get on the ballot in November. Some candidates are still waiting to hear if they are on the ballot and others are confirmed.
Here's an look at who will vie for the 11th congressional district seat:
Chris DeCarlo: Independent candidate Chris DeCarlo of Fairfax is in the process of having his candidacy verified with the necessary 1,000 signatures, according to the Virginia State Board of Elections. DeCarlo has campaigned through rap videos, two of which can be found on his website. He is expected to release a third video in September.
It's his second bid for the seat: He ran unsuccessfully in 2010 against Connolly and Republican Keith Fimian, earning 0.81 percent of the vote.
DeCarlo also campaigned in 2011 for chairman of the Fairfax County Board of Supervisors, and earned 24.73 percent of the vote in his race against Del. David Bulova for the 37th District seat in 2009.
Joseph Galdo: Electrical engineer Joe Galdo, a resident of Fairfax County, has self-financed $461 for his own campaign as of March 31, according to the Center for Responsive Politics. The Virginia State Board of Elections confirmed Galdo will appear on the Nov. 6 ballot representing the Green Party.
Mark Gibson: Fairfax small businessman Mark Gibson's candidacy is in the process of being verified in Richmond, according to the Virginia Board of Elections. A June 18 post by Gibson on his website said his campaign had gathered 1,412 ballot petition signatures. According to his site, Gibson has spent $4,321 on his campaign as of June 15.
"As we wait for validation of 1,000 voter signatures, I just want to thank you and tell you how appreciative I am," he wrote on his website. "Throughout this effort, my focus has been on issues and offering voters a distinct, independent choice for Congress. That focus doesn't — and won't — change."
