If you ask Senator Kerry why he believes Senator Obama will be the best person to answer the '3am phone call', he'll tell you it's about judgment.

It's true that, unlike the other two candidates, Barack Obama has made the correct choice with respect to Iraq and Iran. And his policy of speaking to both friend and foe has been proven by history to be the correct course. Also important to good foreign relations, though, is the proper temperament, and Obama can chalk up a win in that column as well.

Despite Sen. Clinton's claims that she and Sen. McCain are the two candidates who have the experience to react in times of crisis, there is serious concern about what that reaction might be. First, though, two questions. Why is Sen. Clinton defending the Republican nominee over the Democratic candidate, and what, exactly, is her experience? Until recently, the media hasn't challenged her assertions, but lately, they've come under scrutiny.

"I think it's imperative that each of us be able to demonstrate we can cross the commander-in-chief threshold. I believe that I've done that. Certainly, Sen. McCain has done that and you'll have to ask Sen. Obama with respect to his candidacy." -- Hillary Clinton

"I think you'll be able to imagine many things Senator McCain will be able to say. He's never been the president, but he will put forth his lifetime of experience. I will put forth my lifetime of experience. Senator Obama will put forth a speech he made in 2002." -- Hillary Clinton

So, when John McCain picks up the phone at 3 am, how will he react? Maybe he'll belt out a tune. Heck, the song works with a whole lot of Middle Eastern countries. Perhaps he'll insult some world leader's children. Or maybe a simple "f-you" -- click. Keith Olbermann speaks to Salon's Mark Benjamin about military leaders' fears and John McCain's temperament.

I'm not sure why Sen. Clinton believes John McCain is more prepared than Barack Obama to answer that 3 am phone call. Maybe it's a matter of judgment. Or maybe she really does have some of that John McCain 'experience'.
