Does the counting stop when someone concedes ?
If he has conceded and then turns out to be the actual winner can he "take back" his concession ?
A concession is merely a means of showing class and acknowledging that the race is over -- something Rats often have great difficulty in doing.
Tom waited to concede until there was no possible doubt as to the final outcome.
Over 600 thousand late absentee and provisional ballots have already been counted since election night. Out of those ballots Tom gained less than 5 thousand net votes, leaving him still 21 thousand behind Westly. There are less than 100 thousand ballots left to be counted. My spreadsheet projections (which have been quite accurate over the past two weeks) show that Tom will gain perhaps seventeen hundred votes out of those remaining ballots, still leaving him at least 19 thousand short.
Tom has been getting 50.4% of the late absentee and provisional ballots that were cast for him or Westly. He got 49.8% of the ballots that were cast for him or Westly on or before November 5th. He would need to get 61.5% of the remaining (mostly provisional ballots) still to be counted in order to overtake Westly. It's statistically impossible. Tom has lost.
