Rasmussen has him in the mid 40s. It is probably closer to 50%.
Which I think is okay, considering the 27/7 attacks by the MSM and that like many on the right, I haven't "approved" of the performance of ANY president elected since 1984. 100% of the Free Stuff Army will approve of any president who promises them more free stuff, and 100% will disapprove of any president who doesn't. Conservatives/libertarians and progressives see the nature of government and presidents completely differently. No poll takes that into account.
