Obama's approval is down to 53%.
And, in possible 2012 matchups, Obama leads Newt Gingrich 52%-39%; he's ahead of Mike Huckabee 49%-42%; he beats Sarah Palin 53%-41%; and he leads Mitt Romney 50%-39%.
The rule of thumb is that an incumbent under 50% is in trouble.
Obama's under 50% against Huckabee, he's just at 50% against Romney, and he's at 52% or 53% against the two most controversial and divisive Republicans.
Overall, not good during the first hundred day honeymoon.
