Justices Seem Skeptical of Arizona Voter ID Law

Is it trumped by federal voter registration guidelines?

Supreme Court justices expressed some skepticism on Monday about an Arizona law that requires people registering to vote in federal elections to show proof of citizenship.

The legal question before the nine justices is whether the voter registration provision of the 2004 state law is trumped by a federal law, the 1993 National Voter Registration Act, which outlines various ways in which people can register to vote in federal elections.

That law requires no proof of citizenship. Would-be voters simply sign a statement saying they are citizens.
