America's Republican and Democratic parties are scrambling to make sure their supporters turn out to vote in Tuesday's U.S. elections.
The nation's two main political parties have sent out thousands of volunteers to states with the most hotly contested congressional races.
Polls by major media outlets released Sunday indicate opposition Democrats have an edge and may have enough support to take control of the 435-seat House of Representatives. But the polls also indicate the majority Republican Party has gained some ground over the past two weeks.
Democrats would need to have a net gain of six seats to take control of the 100-seat Senate. Polls show there are a number of extremely close Senate races across the country, including Virginia, Missouri, Montana and Rhode Island.
The latest polls show the war in Iraq is still the dominant issue on voters' minds. Democrats have said a victory for their party would mean a change in strategy in Iraq.
President Bush continues to campaign for Republicans, and is scheduled to make stops in Florida, Arkansas and Texas on Monday. Sunday, he told supporters in the western state of Nebraska that "the world is better off" for his decision to remove Sadam Hussein from power.
Members of the House of Representatives serve two-year terms, and every seat is contested every two years. Senators serve six-year terms, with one-third of those seats contested every two years.
