Hillary Clinton has a 3 a.m. ad on TV, and so does Barack Obama.

Hers: "It's 3am and your children are safe and asleep. But there's a phone in the White House and it's ringing. Something's happening in the world. Your vote will decide who answers that call. Whether it's someone who already knows the world's leaders, knows the military — someone tested and ready to lead in a dangerous world. It's 3am and your children are safe and asleep. Who do you want answering the phone?"

His: "It's 3 a.m. and your children are safe and asleep. But there's a phone ringing in the White House. Something's happening in the world. When that call gets answered, shouldn't the president be the one — the only one — who had judgment and courage to oppose the Iraq war from the start... Who understood the real threat to America was al-Qaeda, in Afghanistan, not Iraq. Who led the effort to secure loose nuclear weapons around the globe... In a dangerous world, it's judgment that matters."
