As for other things they can blow hot air about, how about this quote from Dave Winer:

Analysts and pols are hemming and hawing about the propriety of Halliburton being given the oil industry of Iraq. Come on, this is too easy. Even if it had been put up for bid, Halliburton shouldn't have been considered because the vice-president was the CEO of the company before running for office. And it wasn't put up for bid, they just gave the contract to Halliburton. Here's strike three -- they still haven't found any weapons of mass destruction in Iraq. This is a scandal.

I've seen quite a number of news stories about congressional Democrats being up in arms about the aircraft carrier thing but very few where they've mentioned any of the points in Dave Winer's post. They truly deserve to lose the next elections with their incompetent asses.
