The final presidential debate between Barack Obama and John McCain sparked intense discussion, particularly regarding McCain's aggressive tactics and the effectiveness of negative campaigning. Observers noted that McCain appeared increasingly desperate, while Obama maintained composure, which many interpreted as a reflection of their respective leadership qualities. There was speculation on whether McCain would resort to personal attacks, with some arguing that such a strategy could backfire, especially given public fatigue with negativity and a desire for substantive discussions on issues like the economy.The debate featured the controversial figure "Joe the Plumber," whose concerns about Obama's tax plan became a focal point. However, it was revealed that Joe lacked a plumber's license and had financial issues, raising questions about his credibility. McCain's reliance on Joe's narrative was criticized, with some suggesting it highlighted a disconnect with voters' realities. Overall, the debate was characterized by a perception that Obama outperformed McCain, leading to predictions of a widening gap in support for Obama as the election approached.
