Supreme Court Seems Skeptical of Keeping Signatures Private

The Supreme Court appeared critical Wednesday of the claim that Washington state voters who signed a petition to overturn a gay-rights law are entitled to anonymity. Justice Antonin Scalia scoffed at what he called the “touchy-feely” arguments against disclosing their names, saying “you can’t run a democracy this way, with everybody being afraid of having his political positions known.”
“Running a democracy takes a certain amount of civic courage,” Scalia said. “And the First Amendment does not protect you from criticism or even nasty phone calls when you exercise your political rights to legislate, or to take part in the legislative process.”

I don’t think that’s correct, we’ve been hearing for months that we shouldn’t criticize concress-critters for their votes. I thought they have the right to do as they please and we have the right to keep our mouths shut?
