WASHINGTON (AP) -- The Democratic lawmaker in charge of increasing the party's majority in the House says he's confident of solid gains, even though there has been a tightening in several races.
Maryland Rep. Chris Van Hollen says he's cautious because so many House races are being fought in GOP-leaning districts, so he's not predicting the 20-plus seat gains that others see.
Van Hollen says that a 10 to 15 seat gain would be a solid win.
He says to expect a big night for Democrats if they pick up a GOP seat in Indiana, where polls close at 7 p.m.
But if endangered Democratic incumbents lose battles in Pennsylvania and New Hampshire, Democratic gains would be more limited.
All 435 House seats are up for grabs tonight.
Democrats currently hold a 36-seat edge.
