To someone in the legal profession, nomination to the Supreme Court may be one of the most prestigious developments in his or her career, and politicians wrangle over Supreme Court nominees' views and ideological leanings each time someone new is nominated.
But by and large, polls show the public knows very little about these nominees.
In a, about two weeks after Elena Kagan was nominated to the Supreme Court, three in four Americans said they had no opinion of Kagan. Just 16 percent had a favorable opinion of her, and 11 percent were unfavorable.
But Kagan is no less well-known than previous nominees. Before their confirmation hearings, four in five had no opinion of Samuel Alito, and 68 percent had no opinion of John Roberts. Although she was better-known than other nominees, more than half had no opinion of Sonia Sotomayor.
A poll conducted by the Associated Press/GfK in mid-June found a similar lack of familiarity with Kagan: 21 percent were favorable towards her, 17 percent unfavorable - but 63 percent hadn't heard enough about her to have an opinion.
Views of Supreme Court nominees have generally been heavily influenced by political partisanship. Recent justices nominated by Republican presidents - Samuel Alito, John Roberts, Clarence Thomas, David Souter and Robert Bork -- received more support from rank and file Republicans than Democrats.
Likewise, Sonia Sotomayor -- nominated by a Democratic president -- was viewed more positively by Democrats than Republicans. The same holds true for Elena Kagan in the recent CBS News Poll: 31 percent of Democrats had a favorable opinion of her, compared to just 7 percent of Republicans.
And the Senate confirmation hearings don't always provide Americans with the opportunity to form an opinion of some nominees. In a poll conducted after his confirmation hearings, 33 percent felt that the Senate should confirm Samuel Alito, 18 percent felt it should not, but a 46 percent plurality couldn't say.
As John Roberts' hearings wound down, a CBS News/New York Times Poll found that 63 percent couldn't say whether he should be confirmed or not.
The confirmation hearings do provide an opportunity for the public to hear the nominees' positions on issues - something Americans have long felt is important.
In 2009, by more than two to one the public said that the Senate should consider the nominee's personal views on major issues the Supreme Court may decide in addition to his or her legal background and experience. Thirty percent said legal qualifications only should be considered while 62 percent said positions on issues should also be considered.
Those figures have been similar in CBS News Polls going as far back as 1987.
Other polling data have also found a lack of familiarity with members of the Supreme Court. A recent telephone poll conducted on behalf of Findlaw.com found that just 35 percent of Americans could name even one of the justices now sitting on the Supreme Court.
