National: Mail-in ballots: the hanging chads of 2012? | Reuters
Sloppy signatures on mail-in ballots might prove to be the hanging chads of the 2012 election. As Republicans and Democrats raise alarms about potential voter fraud and voter suppression, mail-in ballots have boomed as an uncontroversial form of convenient, inexpensive voting. In the critical swing states of Ohio and Florida, more than a fifth of voters chose the mail-in option 2010. In Colorado, another battleground, the number was nearly two-thirds. But there may be controversy to come. For a variety of reasons, mail-in ballots are much more likely to be rejected than conventional, in-person votes.
