Are you? Because I can understand the occasional one-off misstatement from any candidate, whether its McCain or Obama. But when a candidate starts repeating his errors (such as McCain's Czechoslovakia which he's said over and over) or Sunni/Shia problem (which he's made at least four times) that indicates that the person really doesn't understand.
And how many times has your boy told us the surge was a mistake? Will you admit that YOUR boy doesn't understand?
I realize that most people are only able to understand soundbites, but the surge happened primarily in Baghdad, while Al Anbar which had minimal intervention saw its violence go down. If you're interested in how things are actually going, which based on your "your boy" comment I don't think you are, you can check the statistics here: http://icasualties.org/oif/ To get effective policies you have to have a candidate who understands these very important details.
