The longest and most expensive presidential race in US history has entered its final full day. Senator John McCain is campaigning in Tennessee, Pennsylvania, Indiana, New Mexico, Nevada and Arizona in an attempt to pull off an upset victory. The latest Washington Post-ABC News poll shows Senator Barack Obama has an 11 percent lead among likely voters. If elected, Obama will become the nation’s first African American president. The Illinois senator is heading today to Virginia, North Carolina and Florida, three states won by President Bush in 2004. Over the weekend Obama told supporters that now is not the time to let up.

Sen. Barack Obama: “My faith in the American people has been vindicated. That’s how we’ve come so far. That’s how we’ve come so close. Because of you, because of your hard work, because of your efforts, because of your commitment, because of your support. That’s how we’ll change this country. With your help. And that’s why we can’t afford to slow down, sit back or let up one minute, one second, in these last few days, not now, not when there’s so much at stake.”
