What it does tell us is that Democrats who try to tie Republicans to the Bush years may not have the same success they had a few years ago. Bush is much more of a neutral figure in the eyes of Americans.
At the same time, Obama and his fellow Democrats’ ability to lay the economic situation at the feet of his predecessor is weakened. By 2016, it’s possible that the majority of Americans will hold Obama responsible for the state of the economy."
