A 1985 graduate of the American University in Washington, D.C., Ebbin was a Fellow at the University of Virginia's Sorensen Institute of Political Leadership in 2000. A longtime Democratic Party activist, Ebbin spent a decade on the party's state central committee and was a delegate to both the 2000 and 2004 Democratic national conventions. In 2012, Ebbin completed program for Senior Executives in State and Local Government as a Leadership Fellow.
He first sought the 49th district seat in 2003, narrowly winning a five-person Democratic primary and facing no Republican opponent in the general election. He took office in January 2004 and was re-elected unopposed in 2005. Ebbin faced only an Independent Green opponent in 2007, winning easily, and ran unopposed in 2009. The district includes a large part of South Arlington, the Del Ray and Arlandria portions of the City of Alexandria and parts of Bailey's Crossroads in Fairfax County.
State Senate
Ebbin decided to give up his seat in the House of Delegates to run for the Virginia State Senate in 2011, following Patsy Ticer's announcement that she would not seek re-election. He ran in the 30th district, comprising parts of Arlington, Alexandria and Fairfax County; the district leans heavily Democratic. He faced a heated Democratic primary election held on August 23, 2011, with two opponents: Rob Krupicka, a member of the Alexandria city council, and Libby Garvey, a member of the Arlington school board. Krupicka, who led in fundraising, was widely considered the favorite but Ebbin prevailed narrowly in what local newspapers called an "upset" and a "shocker". Ebbin took 39% of the vote to Krupicka's 36% and Garvey's 25% – a margin of 335 votes. The 30th district race was the second most expensive primary in the state, with the three Democratic candidates raising a combined $746,000. In the general election, Ebbin faced Republican candidate Tim McGhee and prevailed easily. He took office as a Virginia state senator on January 11, 2012. Ebbin serves on five Senate Committees: Finance and Appropriations; Commerce and Labor; Privileges & Elections; General Laws and Technology; and the Transportation Committee. He serves on a number of Commissions and interim Comittees including the Task Force to Commemorate the Centennial Anniversary of Women's Right to Vote, the Joint Commission on Administrative Rules, the Northern Virginia Transportation Commission, and the Joint Subcommittee to Evaluate Taxation Preferences. Adam also serves as the Vice-Chairman of the Joint Commission on Technology and Science and as the Co-Chair of the General Assembly Gun Violence Prevention Caucus.

2014 Congressional Campaign
On January 30, 2014, Ebbin announced his candidacy in the Democratic primary for the 8th Congressional district seat being vacated by Congressman Jim Moran. The 8th Congressional District is Virginia's most Democratic district, with a Cook Partisan Voting Index of D+21, and one of the most Democratic white-majority districts in the South. The heavily contested Democratic primary drew a number of challengers, including former Lt. Governor Don Beyer, State Delegate Patrick Hope, former Northern Virginia Urban League Chief Lavern Chatman, mayor of Alexandria William D. Euille, radio-talk show host Mark Levine, and Virginia Tech professor Derek Hyra. Ebbin finished third in the June 10, 2014 Democratic primary with 6,262 votes, while Beyer won the primary with 17,783 votes. Beyer went on to win the general election on November 7, 2014.
