Wow, the candidates are really playing nice tonight. They're respectful, kidding with each other... The new wrinkle to have candidates ask each other questions was a good idea, and each had the effect of displaying substantial unity among the three on the stage.
Really, though, shouldn't it be this way? On policy, opposition, and most other things, they're not far apart. It's mostly personality that keeps them apart, but it needn't.
MSNBC, by the way, shortchanged us by ruling what was clearly a clarification on Obama's part as "his question." I'm guessing his prepared question, presumably to Clinton, would have been much more edifying. Maybe he'll try to sneak it in later.
