A new Quinnipiac poll suggests that Sen. Martinez (R-FL) may still be suffering in public opinion polling as a result of his prominent support of the "grand bargain": his approval rating has fallen to 36% and his disapproval rating has risen 4 points over the last month or so to 38%. Only 49% of Republicans approve of the job he's doing; 48% of Republicans approve of the job that Florida's Democratic senator Bill Nelson is doing.
