Supreme Court says California must allow in-home prayer meetings Progressive group ramps up pressure on Justice Breyer to retire MORE performed well in another poll on Thursday, as a Quinnipiac survey found that 55 percent of respondents approve of her nomination to the Supreme Court.

A quarter of respondents in the poll disapproved of the nomination.

Sotomayor has performed well in most polls following her nomination. A recent Gallup poll found that a similar percentage - 54 - say Sotomayor should be confirmed.

The Quinnipiac poll found that Sotomayor's approval rating has remained constant over the last week, and indication that conservative attacks may not be working.

"So far the Republicans have barely laid a glove on Supreme Court nominee Sonia Sotomayor," said Peter Brown, assistant polling director at Quinnipiac. "There may be disputes within the Beltway about her nomination, but she is still playing well in Peoria."

Democrats approve of Sotomayor's nomination by a 80 percent to 5 percent margin, while Republican disapprove of it 47 percent to 30 percent.

Here is a breakdown of Sotomayor's approval rating among key demographics:
49 - 29 percent among white voters;
85 - 2 percent among black voters;
58 - 24 percent among Hispanic voters;
51 - 26 percent among white Catholics;
66 - 18 percent among Jews;
43 - 37 percent among white Protestants
White evangelical Christians oppose the nomination 41 - 35 percent.

Notably, Sotomayor hasn't performed well in every poll. Another Quinnipiac poll earlier this week found that a strong majority disagree with her ruling in the controversial Ricci case.

There was a margin of error of plus or minus 2 percent in the survey.
