Washington, D.C. ? The Supreme Court appeared ready Wednesday to uphold the nation’s strictest requirement that voters show photo identification before casting a ballot.

The justices are faced with a partisan dispute that echoes the bitterly divided decision that sealed the 2000 presidential election for George W. Bush. Now, as then, the court seemed divided along ideological lines.

Wednesday’s arguments were over a challenge to an Indiana law, passed in 2005, that is backed by Republicans as a prudent way to deter voter fraud. Democrats and civil rights groups oppose the law as unconstitutional and call it a thinly veiled effort to discourage elderly, poor and minority voters – those most likely to lack proper ID and who tend to vote for Democrats.
