Well, this is rich: Indiana Secretary of State Todd Rokita lobbied for, got, and defended one of the strictest photo ID laws in the country. He was also one of those screaming the loudest about the evil ACORN, defilers of the voting rolls and villains extraordinare. So guess what happened? Rokita's own absentee ballot has been challenged. Seems his sloppy signature did not match his neatly penned one on file, not to mention he signed his ballot "Todd" instead of the correct "Theodore."
More on the Indiana law in question from the SPO archives here and here and on ACORN here.
