FILE - In this May 18, 2010 file photo, Mark Critz, then-Democratic congressional candidate is seen in Johnstown, Pa. House Democrats have reserved more than $32 million in ad time in districts across the country, giving an early sketch of the race for control of the House. Broadly, the ad reservations show that House Democrats will try to regain control of the chamber in many of the same states President Barack Obama must win to get re-elected in November.
