The Supreme Court is evaluating a law that requires voters to show a photo identification.

But a new poll shows many Americans have already made their decision -- and they're overwhelmingly in favor of it.

The Washington Times reports that 67-percent say the government should make voters show photo I.D. before casting their ballot.

More than 75-percent of Republicans support the requirement, saying it cuts down on voter fraud.

Democrat lawmakers have opposed it, saying it discriminates against the poor and minorities. But a majority of Democrat and Independent voters - 63-percent - supported the requirement.
