Ruth Bader Ginsburg and Antonin Scalia always exercise their right to vote, and John Roberts goes to the polls only for general elections, the Washington Post reports. Six of the nine Supreme Court justices—five in Virginia, one in DC—are eligible to participate in today’s primaries, and the chief justice is likely qualified in Maryland.
Because he's designated a “confidential voter,” Roberts' records aren’t public. David Souter is a registered New Hampshire Republican but didn’t vote in the primary, and Stephen Breyer cast a Democratic ballot in Massachusetts on Super Tuesday. Virginians don’t register by party, lending a bit of mystery to the high court’s political leanings.
