Historically, conservatives argued for a narrow approach to standing. There were practical as well as legal reasons for this: When courts were less sympathetic to conservative causes, as in the years of the Warren and Burger Courts, there were good reasons to keep progressive social movements and individual plaintiffs out of court. Now that Donald Trump has reshaped the federal judiciary, the roles have reversed: Conservatives are the ones promoting exotic and broad new ideas about standing—and rushing to settle issues in federal court they fear they would lose if voters were given the right to decide.
