Americans have heard lots this week about the voter-registration exertions of the liberal non-profit group ACORN (Association of Community Organizations for Reform Now), whose political arm has endorsed Barack Obama. Zeal for the task at hand is one thing, but ACORN’s efforts to sign up potential Obama voters are breathtakingly rife with allegations of fraud. Nearly 4,000 voter applications submitted by ACORN were deemed tainted in one county in Ohio. In Florida there was a report of an application from Mickey Mouse, stamped with ACORN’s logo. So much for election integrity. Another sobering fact: Nationwide, ACORN reportedly has registered more than 1.3 million new voters. Some analysts suggest looking to Iraq and Afghanistan for a solution — implementing “purple finger” rules for U.S. elections to prevent individuals from voting more than once. Interesting idea.
