Mark Murray reports counties will begin recanvassing the vote on Friday, although some counties will begin that as early as today.
The next step is counting absentee and military overseas
ballots. Reports suggest as many as 10,000 absentee ballots were requested. These need to be postmarked by Election Day and received by April 7. Military ballots must be postmarked by Election Day and received by
April 13.
The bottom line is that it's highly unlikely a winner will emerge until April 13.
