A new poll shows Governor Tom Corbett's job-approval rating is lower than ever.
 
The Quinnipiac University survey released Tuesday found that voters disapprove of the Republican's performance, 47-percent to 36-percent. That's a sharp reversal since September, when Corbett's approval rating peaked at 50-percent, compared with 32-percent who disapproved.
 
The numbers coincide with signs of discontent among fellow Republicans over Corbett's leadership and unrelenting Democratic criticism of his spending cuts in education and social services.
 
The telephone survey of 997 voters was conducted from June 5th to June 10th, The margin of sampling error was plus or minus 3.1 percentage points.
