Kramer was pursuing a career in computer engineering when he first entered politics in an ill-fated independent run for a seat in the U.S. House of Representatives (Maryland, 5th District) in 1992. Later he moved to Howard County, Maryland and became involved with the local Green Party.
In 2003, he became an Alternate Delegate from Maryland to the Green Party's Coordinating Committee (later Green National Committee), and was elected as a full Delegate in 2004. In 2005, he was elected to the Steering Committee of that body, serving as a co-Chair of the national party. He was also asked to help lead a group working to reform the Presidential nominating process of the Green Party in the same year.
He is currently one of the Green Party's leading advocates for the impeachment of George W. Bush, having appeared at conferences in Washington, D.C. and New York in 2007 to speak on the topic. The Green National Committee passed a resolution in favor of impeachment of George W. Bush (and Vice President Dick Cheney) in 2003.
In addition to his technical and political careers, Kramer has a number of eclectic pursuits. As an active sportsman and game hobbyist, he is a former soccer coach and co-authored a rule book for the Hero System. As an academic, he is Listmaster Emeritus of the Flags of the World mailing list. Kramer is also involved in community theater, both as an actor and as a director on the corporate board of a theater troupe in Prince George's County, Maryland.
Kramer was married in 1991, and has two daughters.
