It is the very first statewide election with the new voting machines. I was surprised nothing seemed to have gone wrong.
And these things happen all the time outside of close elections, too. For example, Connecticut found thousands of ballots cast in the 2008 election well into 2009 and added them to the vote totals. You never heard about it because no races' results were affected.
Case in point:
