Democratic activist and same-sex marriage proponent Sean Eldridge has just filed forms with the Federal Elections Commission announcing his intent to run for Congress. Eldridge, who will run for the House of Representatives as a Democrat, has a major Facebook connection.

In fact, he’s married to Facebook co-founder Chris Hughes.

Hughes and Eldridge married last July in a ceremony attended by other Facebook notables Mark Zuckerberg and Sean Parker. It was also attended by some members of Congress, including House Minority Leader Nancy Pelosi.

Eldridge is the President of Hudson River Ventures, a small investment firm, and is a senior advisor at the Freedom to Marry campaign. In 2012, he served as a delegate to the Democratic National Convention.

He would be seeking New York’s 19th District, which lies north of NYC and south of the capital, Albany. Its seat is currently held by Republican Chris Gibson, a retired Army Colonel who won reelection in 2012 by a six point percent margin. However, the district has voted for President Obama twice now – the latest in 2012 by a six point margin (52 to 46 over Mitt Romney).
