State Sen. Michael J. Stack 3d, the Philadelphia Democrat who had been weighing a bid for governor, announced Wednesday his candidacy for lieutenant governor.
Although Republican Gov. Corbett has struggled in the polls and is seen as vulnerable, Stack, 50, would have faced daunting competition for the Democratic nomination for governor.
Stack now confronts a less formidable field for the right to challenge incumbent James Cawley, a Bucks County Republican.
U.S. Rep. Robert Brady, the Philadelphia Democratic Party chairman, will serve as honorary cochair of Stack's campaign. State Sen. Shirley Kitchen, another city Democrat, will also serve as honorary cochair.
