The two people in question have been PM'd, will see what the outcome is and get a new competition up asap
On a general note, If I'm about when I say it's going to end, I take a reading at that time and ignore any future votes (it's never really an issue as it's not usually this close!), but as I can't control when the actual poll closes, if I miss the time I have no idea who was winning at the scheduled end time.
In future I will just let the poll run for however long the mod/admin has set it to run for, that way we won't have any problems
