WASHINGTON (AP) - Democrats and Republicans are spending millions of dollars and airing thousands of TV commercials as they battle for the House's 435 seats.
But the Election Day result is likely to look familiar.
Democrats may erode the GOP majority slightly but they seem unlikely to gain the 25 additional seats they need to take control of the chamber.
Republicans have a money advantage and are using it to link Democratic candidates to President Barack Obama's economic stimulus and health care laws.
Democrats are accusing Republicans of trying to dismantle Medicare and use the savings to pay for tax cuts for the rich.
Both sides are trying to figure out the impact GOP presidential candidate Mitt Romney's recent campaign struggles will have on House races. So far that seems limited.
