Not all Bush's fault,it was mostly Barney Frank and all his little buddies de-regulating the money hungry banks that caused most of this.(some blame does go to Bush). It could be cleaned up faster than Nobama has,Reagan inherited a worse recession and un-employment and had significant progress in the right direction in his first term, (showing my age but I was around through that one also ) so it can be done.
I'll never say Romney was the right man for the job, for all anyone knows he could have made it worse, it's just with Obama's socialist thinking and lack of progress not much hope for the future.
