Obama Fights To Save Democratic Majorities On Election Day

President Barack Obama made a last-ditch effort to save the Democratic majorities in Congress on Tuesday, as voters seemed poised to deliver landslide victories to the Republican Party.

He phoned in to three high-profile radio shows and taped a message for AOL users, saying his ""ability to work on behalf of middle-class families is going to be hampered if I do not have people in Congress who want to cooperate.""

But polls suggest that's just what the president won't get in these elections, the most expensive midterms in history.

Polls indicate a dissatisfied electorate could clean house -- literally -- by tossing out the Democratic majority in the House of Representatives and possibly doing the same in the Senate.

Losses by the governing party are common in the first midterm election it faces, but the shift Tuesday could rival or match historic levels dating back decades.

Unemployment -- at a rate of 9.6 percent amid a slow recovery from economic recession -- has been the dominant issue, with Republicans accusing Obama and the Democrats of pushing through expensive policies that have expanded government without solving the problem.

Obama has led Democrats in defending his record, saying that steps such as the economic stimulus bill and auto industry bailout were necessary to prevent a depression, while health care reform and Wall Street reform will lay the foundation for sustainable future growth.

Democratic Party Chairman Tim Kaine said Tuesday that party candidates will still pose a challenge to Republicans. ""While I think we've got the headwind we're running against, we're not throwing in the towel,"" Kaine told CNN's ""American Morning."""
