Only 28 percent have a favorable view of the GOP, the worst rating Gallup has ever registered for a political party.
It's also a 10 percent plunge from Gallup's last poll in September, when 38 percent had a favorable view of Republicans.
A strong majority, 62 percent, have a negative view of the GOP, according to the survey.
“The Republican Party is clearly taking a bigger political hit from Americans thus far in the unfolding saga,” Gallup analyst Andrew Dugan wrote. “The Republican Party's current strategy in the fiscal debates may not be paying dividends.”
Only 43 percent said they have a favorable view of the Democratic Party, but that’s 15-percentage points better than the GOP, and slightly better than the Democratic low mark of 41 percent in 2010.
A plurality, 49 percent, said they have a negative view of the Democratic Party.
Gallup has been conducing the survey since 1992. Its previous low ranking of 31 percent was logged by Republicans at the end of the George W. Bush administration.
Gallup’s is the latest in a string of bad polls for Republicans. Survey data consistently finds that the public blames the GOP for the unpopular government shutdown.
Republicans are also hurt by splits within their own party.
“Self-identified Republicans are more than twice as likely to view their own party unfavorably (27%) as Democrats are to see their own party unfavorably (13%),” Dugan wrote.
The number of Republicans that are dissatisfied with the GOP is up 8-percentage points since September.
The Gallup poll of 1,028 adults was conducted between Oct. 3-6 and has a 4-percentage point margin of error.
