LOL Sheeesh Grun, we're discussing what might happen in the future, not what happened in the past. Like it or not we're in Iraq for better or for worse, and the current administration was elected on the promise of maintaining the status quo...it's what more voters than in previous election voted for.
My take on it is that even if it becomes a Viet Nam style war, and public opinion turns against Iraq, the Republicans can run McCain under the "get US out of Iraq" to counter any Democrat running under the same promise, and win in 2008.
In fact it might even help the Republicans to prolong the Iraq war, as Bush is a lame duck anyway, up until 2008 so McCain can play on his "maverick" image....I'm ashamed to admit that if this scenario plays out I'd still vote for McCain. How jacked up is that?
