"It’s the War"
And, yes, to echo Atrios the tendency of many analysts to somehow forget about Iraq when talking about how Obama managed to topple the Clinton machine is pretty bizarre. Clearly, Iraq alone wasn’t enough to carry Obama to victory. But had Clinton voted against the war in 2002 there would have been no Obama challenge — it would have been a senseless and absurd thing to do. In short — no war, no Obama.
Denying this reality seems to be part of the continuing hawk effort to avoid any accountability for the war. At the end of the day, Hillary Clinton had (and has) much more credibility with the liberal base than does the average person who shares her position on the war. If she can be held accountable, and if John McCain (until very recently the most popular politician in America) can be held accountable, then the sky’s the limit.
