Pennsylvania's law requiring people to show identification before they vote has been effectively unenforceable for a year now. But on Friday, a state court found it was actually unconstitutional, and threw it out. Commonwealth Court Judge Bernard McGinley ruled that the law "unreasonably burdens the right to vote." And besides, as the Associated Press points out, "administration officials acknowledged that they knew of no examples of voter impersonation" that would make the law necessary. Supporters of the law have said they'll appeal, but for now the ruling means many Pennsylvania elections will continue to be an uphill battle for Republicans.
