One instant boost i see for the economy if Romney pulls this out is in the natural resource sector. He will undoubtably get the keystone pipeline going which itself will equal quite a few jobs and reduce some of our foreign oil dependency. And then there is ANWR. This is the real ticket to our domestic oil production and lots of jobs and tax revenue. So i don't see how the economy could do anything but go up with these two things alone. Then add in the fact that businessowners will be much more comfortable without Obama and this should lead to them being more willing to expand.
