Supreme Court Nominations: Senate Floor Procedure and Practice, 1789-2011 [March 11, 2011] [open pdf - 390KB]
"From 1789 through 2009, the President submitted to the Senate 160 nominations for positions on the Supreme Court. Of these nominations, 148 received action on the floor of the Senate, and 124 were confirmed. On August 5, 2010, the Senate confirmed the nomination of Solicitor General Elana Kagan to be an Associate Justice of the Supreme Court, making her the 124th Justice on the Court. […] Of the 124 votes by which the Senate confirmed nominees, 73 took place by voice vote and 51 by roll call, but on only 26 of the roll calls did 10 or more Senators vote against. Of the 36 nominations not confirmed, the Senate rejected 11 outright, and 12 others never received floor consideration (some, apparently because of opposition; others were withdrawn). The remaining 13 nominations reached the floor but never received a final vote, usually because some procedural action terminated consideration before a vote could occur (and the President later withdrew some of these). Including those that received incomplete consideration, were rejected, or drew more than 10 negative votes, just 50 of the 160 total nominations experienced opposition that might be called 'significant.'"
