Sounds like a quote from the guy in your tagline.
When the public turns on a war effort they helped to start by cheering it on in overwhelming numbers, and they turn on it based on endless lies and propaganda, politicans who know better have an obligation to counter those lies and propaganda. Not just roll with it.
These guys are a disgrace. So are the constituents who've lost the stomach to fight this war (or technically, to occasionally watch on their televisions as other men fight it).
Why, because they see that the polls show 60 percent of Americans against the war? These guys are politicians who maybe don't want the GOP to be utterly destroyed at the next election, even more than at the last election (in which Iraq was a major factor for many voters). I don't see it as a "disgrace" to want to keep the Democrats from winning a landslide in 2008.
It's a political reality. Ask Rick Santorum.
