(CNN) - A new national poll suggests that by a margin of greater than two to one, Americans approve of President Barack Obama's nomination of Sonia Sotomayor to the U.S. Supreme Court.
Fifty-five percent of those questioned in a Quinnipiac University survey released Thursday say they support the Sotomayor nomination, with one in four opposed and one in five not sure. The poll was conducted over a seven-day period starting on May 26, the day Obama announced his high court nomination, and appears to be the largest survey conducted so far on the subject.
The poll indicates that Democrats overwhelmingly approve the nomination, independents favor it 53 percent to 26 percent, and Republicans oppose it 47 percent to 30 percent.
"Since her nomination nine days ago, her level of support with the American people has been constant," Peter Brown, assistant director of the Quinnipiac University Polling Institute, said in a statement. "This is an indication that criticism from some conservatives and Republicans has not struck a chord with voters - at least not yet."
The survey suggests Americans are split when it comes to Sotomayor's legal qualifications vs. the federal appeals court judge's views. Forty-six percent of those questioned say senators should only consider Sotomayor's legal qualifications in deciding whether to confirm her, with 44 percent saying senators should consider her views on such issues as affirmative action and abortion.
There's a partisan split on this question, with a majority of Democrats responding that only Sotomayor's qualifications should be considered in the confirmation process, and a majority of Republicans questioned in the poll saying that the judge's views on issues should be considered.
If confirmed by the Senate, Sotomayor would become the first Hispanic or Latino justice on the Supreme Court. The poll indicates that one-third of Americans say that was a very important factor in the president's nomination of Sotomayor, with one in three say it was somewhat important. One in ten feels it was not too important and 17 percent say it was not important at all.
A majority of those questioned say Sotomayor's legal qualifications for the job are more important than making the Supreme Court look like the rest of the nation in terms of race, religion, ethnicity and gender. Only 8 percent indicated that legal qualifications are less important, with three in ten saying they are equally important.
Sxity-two percent of Americans approve of the U.S Supreme Court, the highest approval ever measured in a Quinnipiac survey.
The Quinnipiac University poll was conducted May 26-June 1, with 3,097 registered voters nationwide questioned by telephone. The survey's sampling error is plus or minus 1.8 percentage points.
