I said it was due "almost" entirely meaning there were other reasons just none as significant. I stand by that assessment, If Iraq was going well the Rs would at the least have kept control of Congress very possibly have gained.
We will agree to disagree. Historically speaking, I seriously doubt that we would have gained seats. Also, you fail to give credit to the Dems who did a much better job of candidate selection and voter turnout. We did not just lose seats in federal elections, we also lost 6 governorships and some statehouses.
