Sean Eldridge, husband of Facebook co-founder and New Republic publisher Chris Hughes, has filed papers to run for New York's 19th House district.

Should he run, the 26-year-old Eldridge would face Rep. Chris Gibson (R), first elected to the House in 2010. The well-liked congressman won in 2012 by seven points even though President Obama carried the district, which became significantly more Democratic under the post-2010 map.

Eldridge leads an investment fund, Hudson River Ventures, that specializes in local food-and-drink companies. He and Hughes financed a campaign last year, Protect Our Democracy, to push for publicly financed elections. The super PAC got involved in a local state Senate race, helping Democrat Cecilia Tkaczyk win. And he's a senior adviser at Freedom to Marry, a gay marriage advocacy group, where he previously served as spokesman and political director.

Gibson is a retired Army colonel and a lifelong resident of the Hudson Valley. Eldridge grew up in Ohio; he and Hughes bought an estate in Garrison, N.Y. two years ago.

New York's Capitol Tonight first reported on Eldridge's statement of candidacy.
