With the White House race still too close to call, Republican George W Bush and Democrat Al Gore embarked on frenzied final campaign swings in the hope of dislodging the handful of votes that could prove decisive. Both camps upped the pace of the campaign, announcing grueling multi-state marathon's, in a clear indication that neither candidate comes close to feeling complacency just hours away from their White House showdown at the ballot box. Texas Governor Bush appears to have retained his slender lead in the national polls going into the final campaign day following Sunday’s all-day campaign in Florida, a fiercely contested state run by his brother, Governor Jeb Bush. Gore, who on Saturday acknowledged that he needed a boost when he asked voters in Memphis, Tennessee, to breathe life into this campaign was on a non-stop swing through five key states, starting with Pennsylvania. “I think there's no question this is an election that is going to the finish line tomorrow, and this is probably the only election in modern presidential times when we really don't know the outcome,” said Gore campaign Chairman William Daley. Both the Bush and Gore camps know that the race will be determined by who wins the popular vote in a dozen or so tossup states, including Florida, Pennsylvania, Michigan, and Missouri. Bureau Report
