If you listened to Murtha in detail in the past, you saw a man who frequently rambles with stories of how our military is evil and mistreats its soldiers. He packages it as if he is standing up for his constuents' rights, which is fine. But he takes anecdotal occurences such as a soldier not technically qualifying for a medal, and makes it sound like the US military hates its soldiers. In short, he has been a leftist kook for a long time.
Murtha is, in essence, a Pelosi clone.
