And, yes, what does this headline have to do with the article?
Basically, Murtha is saying the 2008 elections are interfering with any plan to retreat from Iraq because Republicans and Democrats do not want to risk losing their seats. Ergo, democracy, or the democratic process, is interfering with what he wants.
We could either assume he's:
1. Complaining about a side effect of the democratic system that he doesn't like.
2. Suggesting we end democracy because it's inconvenient.
It's subject to interpretation, but I'm going to go with door number one, here.
