WASHINGTON (CNN) -- Delaware Sen. Joe Biden, the ranking Democrat on the Senate Foreign Relations Committee, said Monday the American people can express their dissatisfaction with the Bush Administration's handling of the Iraq war by voting for Democrats on Election Day.

"If the Democrats make significant gains in the United States Senate and take control of the House we will be able to forge a bipartisan consensus for change in Iraq," Biden told reporters Monday. "But if the Republicans hold on and there's not real significant gain for Democrats, I think Bush, Cheney, Rumsfeld will take that as a sign to continue to stay the course."

Biden, who has expressed interest in a potential presidential run, also said "at least two" senior Republicans have told him directly they are prepared to "force a substantial change" in Iraq policy after the election and the Delaware Democrat says he thinks a dozen or more Republicans would be willing to join the effort.
