In a campaign supported by the Koch brothers, Republicans are working to prevent millions of Democrats from voting next year Link .... What has happened this year is the most significant setback to voting rights in this country in a century," says Judith Browne-Dianis, who monitors barriers to voting as co-director of the Advancement Project, a civil rights organization based in Washington, D.C. Republicans have long tried to drive Democratic voters away from the polls. "I don't want everybody to vote," the influential conservative activist Paul Weyrich told a gathering of evangelical leaders in 1980. "As a matter of fact, our leverage in the elections quite candidly goes up as the voting populace goes down." But since the 2010 election, thanks to a conservative advocacy group founded by Weyrich, the GOP's effort to disrupt voting rights has been more widespread and effective than ever. In a systematic campaign orchestrated by the American Legislative Exchange Council – and funded in part by David and Charles Koch, the billionaire brothers who bankrolled the Tea Party – 38 states introduced legislation this year designed to impede voters at every step of the electoral process. .... Even at the time, there was no evidence to back up such outlandish claims. A major probe by the Justice Department between 2002 and 2007 failed to prosecute a single person for going to the polls and impersonating an eligible voter, which the anti-fraud laws are supposedly designed to stop. Out of the 300 million votes cast in that period, federal prosecutors convicted only 86 people for voter fraud – and many of the cases involved immigrants and former felons who were simply unaware of their ineligibility. A much-hyped investigation in Wisconsin, meanwhile, led to the prosecution of only .0007 percent of the local electorate for alleged voter fraud ... In Texas, under "emergency" legislation passed by the GOP-dominated legislature and signed by Gov. Rick Perry, a concealed-weapon permit is considered an acceptable ID but a student ID is not. Republicans in Wisconsin, meanwhile, mandated that students can only vote if their IDs include a current address, birth date, signature and two-year expiration date – requirements that no college or university ID in the state currently meets. As a result, 242,000 students in Wisconsin may lack the documentation required to vote next year. "It's like creating a second class of citizens in terms of who gets to vote," says Analiese Eicher, a Dane County board supervisor.
