One of the cornerstones of the Republican Party’s strategy for winning elections these days is voter suppression, intentionally putting up barriers between eligible voters and the ballot box. The House of Representatives took a shameful step in this direction yesterday, voting largely along party lines for onerous new voter ID requirements. Laws of this kind are unconstitutional, as an array of courts have already held, and profoundly undemocratic. The Senate should not go along with this cynical, un-American electoral strategy.

The bill the House passed yesterday would require people to show photo ID to vote in 2008. Starting in 2010, that photo ID would have to be something like a passport, or an enhanced kind of driver’s license or non-driver’s identification, containing proof of citizenship. This is a level of identification that many Americans simply do not have.

The bill was sold as a means of deterring vote fraud, but that is a phony argument. There is no evidence that a significant number of people are showing up at the polls pretending to be other people, or that a significant number of noncitizens are voting.

Noncitizens, particularly undocumented ones, are so wary of getting into trouble with the law that it is hard to imagine them showing up in any numbers and trying to vote. The real threat of voter fraud on a large scale lies with electronic voting, a threat Congress has refused to do anything about.
