IDEOLOGICAL VALUES AND THE VOTES OF US SUPREME-COURT-JUSTICES REVISITED

Segal and Cover (1989) analyzed the content of newspaper editorials to devise measures of the ideological values of the justices of the U.S. Supreme Court. Because their measures came from sources independent o f the judicial vote, scholars have widely adopted them. This note upda tes, backdates, and extends the Segal and Cover research by adding the two Bush appointees and the seven Roosevelt and four Truman nominees whose service extended beyond the start of the Vinson Court. While we find that the ideological values of the Eisenhower through Bush appoin tees correlate strongly with votes cast in economic and-civil libertie s cases, the results are less robust for justices appointed by Rooseve lt and Truman.
