Anytime McCain wants to highlight Iraq he's welcome to. Not only does it confirm his horrible judgement in supporting the war but it demonstrates he clearly doesn't meet the magical "Commander In Chief Threshold" that we've recently heard so much about. A Republican that thinks standing on George W. Bush's stellar record in Iraq is a positive is clearly living in la-la land.
A McCain visit to Iraq with toady Joe Lieberman in tow is a net plus to the Democratic candidate. We shouldn't be bitching about it. We should be encouraging more of the same.
