Scott holds a little more than a 12,000 vote lead over Nelson. That amounts to an advantage of about 0.15 percentage points, which is well within the 0.25 point margin needed for a manual recount required by Florida law. This margin may seem small, but for recount purposes, it is actually quite large.
According to a FairVote database of statewide recounts from 2000 to 2015, the average recount moves the margin by 0.02 points. Nelson needs the margin to move by nearly eight times as much.
The recount with the largest shift was the Vermont Auditor of Accounts race in 2006. The margin shifted in that by 0.11 points, which is still less than what Nelson needs.
