Corey D. O’Brien is an American politician and member of the Democratic Party. He is a member of the Lackawanna County Board of Commissioners. In 2010, he challenged incumbent Congressman Paul Kanjorski in the May 2010 Democratic primary but lost.
2007 Commissioner election
In 2007, O'Brien and incumbent Democratic Commissioner Mike Washo took on the two incumbent majority commissioners, Republicans, A.J. Munchak and Robert Cordaro. In November, the Washo-O'Brien ticket defeated the Republican ticket, with only Munchak remaining on the board.
2010 Congressional election
He challenged 13-term incumbent Congressman Paul Kanjorski in the May 2010 Democratic primary. O'Brien received 33.9% of the vote, while Brian Kelly received 16.8% of the vote, and Kanjorski won with 49.3% of the vote.  In the general election, Kanjorski was defeated by Republican Lou Barletta.
2011 Commissioner election
In 2011, O'Brien selected Jeanette Mariani, the Mayor of Blakely, as his new running mate after Washo announced his retirement. In the Democratic primary, O'Brien finished with the second-highest vote total, narrowly ahead of former county chief of staff Elizabeth Randol, but behind the top vote getter, former State Representative James Wansacz. In the general election, O'Brien and Wansacz received the two highest vote totals, thus continuing the Democratic majority on the board.
