Should the Petitioners' Names Be Public?

Great article by Dahlia Lithwick about oral arguments in the Supreme Court over Doe vs. Reed. The case concerns whether the names of people who sign a petition to put a measure on ballot should be released to the public. Justice Scalia:

for the first century of our existence, even voting was public—you either did it raising your hand or by voice. . . running a democracy takes a certain amount of civic courage. And the First Amendment does not protect you from criticism or even nasty phone calls when you exercise your political rights to legislate.
