On the campaign trail, Senators Barack Obama and John McCain enter the final weekend of their race focusing on battleground states. On Thursday, McCain addressed supporters in Defiance, Ohio at the start of a two-day bus tour across the state.

Sen. John McCain: “America is worth fighting for. Nothing is inevitable here. We never give up. We never quit. We never hide from history. We make history. Now let’s go win this election and get our country moving again.”

After Ohio, McCain will spend the weekend in Virginia, Pennsylvania, New Hampshire and Missouri. Obama, meanwhile, was in Sarasota, Florida, where he addressed a rally of over 13,000 people.

Sen. Barack Obama: “I can take one more week of John McCain’s attacks, but this country can’t take four more years of the same failed policies. In five days, we can come together as one nation and one people and choose a better history. That’s what’s at stake. That’s what we’re fighting for.”

Obama spoke one day after appearing on Comedy Central’s The Daily Show with Jon Stewart. During the interview, Stewart made light of the so-called Bradley effect, the instance of white voters not selecting an African American candidate after saying they would support him in polls.

Jon Stewart: “Are you concerned, in some respects, you know —- and I don’t even know how to bring this up. Obviously, your mother is from Kansas. She’s a white woman. Your father, African. Are you concerned that you may go into the voting booth and -—”

Sen. Obama: “I won’t know what to do.”

Stewart: “Your white half will all of a sudden decide, 'I can't do this.’”

Sen. Obama: “Yeah. Yeah, it’s a problem.”

Stewart: “What is it?”

Sen. Obama: “I said it’s a problem. I’ve been going through therapy to make sure that I vote properly on the 4th.”
