Nominations to the Supreme Court During Years of Divided and Unified Party Government [March 16, 2016] [open pdf - 240KB]
"This CRS Insight provides data and analysis related to nominations made to the Supreme Court during years of unified and divided party government. Specifically, for the purposes of this Insight, 'unified party government' is defined as when the party of the President is the same as the majority party in the Senate. Conversely, 'divided party government' is defined as when the party of the President is different than the majority party in the Senate. Given that the House of Representatives does not have a formal constitutional role in the selection and confirmation process for Supreme Court Justices, it is not included in the analysis below."
