By that time the domestic opposition was just rolling over and taking it. Admittedly, the 2007-2009 congress was elected on an anti-war, anti-bush platform, but they did little to that end, and their constituents did little to punish them for it. Everybody was tired of the war by then. Chapter 8 in Thomas Ricks's book The Gamble is titled "The Domestic Opposition Collapses." It's also important to point out that the bulk of what is though of as the anti-war left was a movement that opposed the Iraq war. When Obama took office, the war was winding down, and we virtually had a withdrawl timeline, so there wasn't much to protest. Most Americans, including many of the Iraq War protestors, thought that Afghanistan was justified.
