THE POLITICAL ROOTS OF JUDICIAL LEGITIMACY: EXPLAINING THE ENDURING VALIDITY OF THE INSULAR CASES

Political parties fashioned distinctive national platforms to emphasize pro- and anti-imperialist leanings. Members of Congress vociferously disagreed about the status of America’s newly-acquired territories.
