While I've put in a request to the campaign to find out how many ballots are in but uncounted, and how many are out and could potentially still come in by the mail ballot deadline... apparently the math works out that if the ballots break in the same pattern as the early vote, Carter would end up with a victory margin of 15 votes. And that doesn't even include the possibility of any recounts.
Still, a lot of unknowns, but the race for HD 73 is back on the table.
