A new low: Obama's approval down to 45%

This is the first time he’s topped the 50% disapproval mark in our surveys.

There isn’t any one smoking gun to point to in explaining Obama’s diminished standing. In the last month he’s seen small increases in the number of voters disapproving of him among Democrats (from 13% to 16%), Republicans (84% to 88%), and independents (55% to 56%) alike.

The two most troublesome things for Obama in his numbers at this point are his standing among white voters and independents.
