President Obama's First-Term U.S. Circuit and District Court Nominations: An Analysis and Comparison with Presidents Since Reagan [May 2, 2013] [open pdf - 445KB]
"The process by which lower federal court judges are nominated by the President and considered by the Senate is of continuing interest to Congress. Recent Senate debates in Congress over judicial nominations have focused on issues such as the relative degree of success of President Barack Obama's nominees in gaining Senate confirmation (compared with other recent Presidents) as well as the number and percentage of vacant judgeships in the federal judiciary and the effect of delayed judicial appointments on judicial vacancy levels. This report addresses these issues, and others, by providing a statistical analysis of nominations to U.S. circuit and district court judgeships during the first terms of President Obama and his four most recent predecessors."
