After last Tuesday’s D.C. primary, the margin of difference between At-Large frontrunners Councilmember Vincent Orange and Sekou Biddle was a mere 543 votes—1.05 percent of all ballots cast in that race. But that’s not the end of the story.

Tomorrow the D.C. Board of Elections and Ethics will count absentee and provisional ballots, a process that could either widen Orange’s lead or bring Biddle within the margin when a full recount is required. According to board officials, some 2,400 absentee ballots have been received, along with close to 3,000 provisional ballots. (WTOP was first to report the numbers yesterday.)

Once tomorrow’s counting wraps up, the three-person board will meet on April 18 to certify the election—basically, they put their stamp of approval on the final numbers. If the margin of difference is within one percent, a recount is required. But if it’s over the one percent margin, the loser still has the option of requesting a recount. That recount, though, isn’t free—a $50 deposit is due for every precinct to be recounted. (That money is refunded if the recount changes the outcome of the election.)

The At-Large election certainly isn’t over yet.
