"And now, after twenty-one months and three debates, Senator McCain still has not been able to tell the American people a single major thing he'd do differently from George Bush when it comes to the economy. Senator McCain says that we can't spend the next four years waiting for our luck to change, but you understand that the biggest gamble we can take is embracing the same old Bush-McCain policies that have failed us for the last eight years."Obama also is accusing McCain of focusing on dividing Americans, rather than offering solutions to problems, saying that "in one week, you can put an end to the politics that would divide a nation just to win an election; that tries to pit region against region, city against town, Republican against Democrat." Obama has a point. McCain has spent the last several weeks making personal attacks on Obama in advertising and through automated phone calls to voters. The attacks play on a tangential relationship between Obama and former Weather Underground member William Ayers. The two sat on an educational board together, and Obama once attended a campaign event at Ayers' house. Obama has denounced the actions of Ayers in the 1960s.
