It has been a record year for new legislation designed to make it harder for Democrats to vote — 19 laws and two executive actions in 14 states dominated by Republicans, according to a new study by the Brennan Center for Justice. As a result, more than five million eligible voters will have a harder time participating in the 2012 election.

Of course the Republicans passing these laws never acknowledge their real purpose, which is to turn away from the polls people who are more likely to vote Democratic, particularly the young, the poor, the elderly and minorities. They insist that laws requiring government identification cards to vote are only to protect the sanctity of the ballot from unscrupulous voters. Cutting back on early voting, which has been popular among working people who often cannot afford to take off from their jobs on Election Day, will save money, they claim.

None of these explanations are true. There is almost no voting fraud in America. And none of the lawmakers who claim there is have ever been able to document any but the most isolated cases. The only reason Republicans are passing these laws is to give themselves a political edge by suppressing Democratic votes.

The most widespread hurdle has been the demand for photo identification at the polls, a departure from the longstanding practice of using voters’ signatures or household identification like a utility bill. Seven states this year have passed laws requiring strict photo ID to vote, and similar measures were introduced in 27 other states. More than 21 million citizens — 11 percent of the population — do not have government ID cards. Many of them are poor, or elderly, or black and Hispanic and could have a hard time navigating the bureaucracy to get a card.

In Kansas, the secretary of state, Kris Kobach (who also wrote Arizona’s notorious anti-immigrant law), pushed for an ID law on the basis of a list of 221 reported instances of voter fraud in Kansas since 1997. Even if that were true, it would be an infinitesimal percentage of the votes cast during that period, but it is not true.

When The Wichita Eagle looked into the local cases on the list, the newspaper found that almost all were honest mistakes: a parent trying to vote for a student away at college, or signatures on mail-in ballots that didn’t precisely match those on file. In one case of supposed “fraud,” a confused non-citizen was asked at the motor vehicles bureau whether she wanted to fill out a voter registration form, and did so not realizing she was ineligible to vote.

Some of the desperate Republican attempts to keep college students from voting are almost comical in their transparent partisanship. No college ID card in Wisconsin meets the state’s new stringent requirements (as lawmakers knew full well), so the elections board proposed that colleges add stickers to the cards with expiration dates and signatures. Republican lawmakers protested that the stickers would lead to — yes, voter fraud.

Other states are beginning to require documentary proof of citizenship to vote, or are finding other ways to make it harder to register. Some are cutting back on programs allowing early voting, or imposing new restrictions on absentee ballots, alarmed that early voting was popular among black voters supporting Barack Obama in 2008. In all cases, they are abusing the trust placed in them by twisting democracy’s machinery to partisan ends.
