It was about Republicans who tossed off family values and ethics. It was about Republicans who embraced the Washington culture of corruption, pork, lobbying, and all the rest. It was about Republicans who forgot that it was about smaller and better government, not big spending and business as usual. Critical members were targeted for destruction by Democrats, but for the most part, they set themselves up for the targeting.

Democrats who won in close, normally-conservative districts were selected for being moderate, "Blue Dog" candidates.

This was all confirmed by the exit polls. Anybody telling you it was about Iraq, or even Bush, is lying to you.
