The reason they won was by the blood of the victims of al Qaeda:

Al Qaeda has sent a message to leaders of the Democratic party that credit for the defeat of congressional Republicans belongs to the terrorists.
In a portion of the tape from al Qaeda No. 2 man, Ayman al Zawahri, made available only today, Zawahri says he has two messages for American Democrats.
“The first is that you aren’t the ones who won the midterm elections, nor are the Republicans the ones who lost. Rather, the Mujahideen – the Muslim Ummah’s vanguard in Afghanistan and Iraq – are the ones who won, and the American forces and their Crusader allies are the ones who lost,” Zawahri said, according to a full transcript obtained by ABC News.
Zawahri calls on the Democrats to negotiate with him and Osama bin Laden, not others in the Islamic world who Zawahri says cannot help.
“And if you don’t refrain from the foolish American policy of backing Israel, occupying the lands of Islam and stealing the treasures of the Muslims, then await the same fate,” he said.

What I find interesting about this is that it’s the second time they’ve mentioned not negotiating with anyone but them. Do they really think we’re stupid enough to negotiate with them? What is probably happening here is that they know our MSM is stupid enough to think it’s a good thing to negotiate with them and they are giving them the talking points to start pushing for it (the same way the Democrats give them the talking points). “Hey, they’re softening up because they know they are winning. They are ready to negotiate.”
Sounds like one of Clinton’s trial balloons.
