The Presidential Debates – Who Won?

I am always perplexed by the incessant media and internet traffic focused on who won the last debate. Really, why does anyone care? The one and only time the president of the United States engages in any debate is during election season. Never once does he debate against anyone as a part of his official duties. So why do we care whether we elect a president who is good at debate?

Who appeared more confident? Who appeared more “presidential?” Who was more aggressive? Who was more in control?
