If the Republicans do win both houses. They will still not win big enough to over come Vetos, so they will not be able to actually do much at all that Obama does not approve of. So at the end of 2 years if things are not much better. The Dems will all be like. We gave Congressional Republicans 2 years to save us and they failed. Better to split them. De fund Obamacare, Block the agenda and go for both houses and the WH in 2012.
