Nonsense. The midterm election was about Iraq, period. You may want to make this about trade, outsourcing and the economy in general but, as usual, you can't show us anywhere that these things are hurting our economy in any way, shape or form.
Go to the textile districts in the South. See how they voted. CAFTA and MFN allowed cheap shirts from China/Asia to come in and put them out of business. Go to the high tech suburbs (they were strong GOP districts) and see how they voted. H-1B and outsourcing IT jobs to India and China played a role. The war in Iraq only energized the Dems, and the margins the Dems won by are very small in many GOP districts. If the GOP was Reagan Dem and IT worker friendly, the strong economy will produce enough voters to overcome the anti war Dems. Look at Ohio, eastern Tennessee, eastern Kentucky, the Carolinas, many of the red GOP districts flipped by narrow margins because the Dems fielded conservative/economic nationalist candidates that drew enough Reagan Dem blue collar voters from the GOP to win. Even the WSJ acknowledged that economic nationalism is rising and the era of unbridled free trade may be over.
The midterm was about economics. It was about folks having to use a credit card to put gas in their cars and worried about the value of their homes.
A lot of folks who took the President's war updates at face value that progress was being made in Iraq voted Dem because they were unhappy with the way their own lives seemed to be heading.
