Stuart Rothenberg raised his estimate of likely Democratic gains in the House of Representatives from 8-12 seats to 15-20 seats, which would translate to between 218 and 223 seats -- and a majority -- in the next House.
"Our latest race-by-race review of Congressional districts around the country convinces us that a Democratic wave is building and that the party is poised to take control of the House of Representatives in the fall. The only question now is the size of the November wave.

"The national mood remains bleak for Republicans. President George W. Bush’s job performance ratings are terrible, and the public still gives Congress low marks. A majority of Americans continue to tell pollsters that the country is headed in the wrong direction.

"That’s a recipe for a GOP disaster, and there is no reason to believe that things will change dramatically between now and Election Day to improve Republican prospects."
