However, Martin had initially refused to concede, alleging possible voter fraud in Democratic areas. (One example was an allegation of mentally handicapped people casting ballots.) A key piece of evidence, Martin claimed, was that the late Carnahan surge had taken place in just seven key precincts -- however, it later became clear that the surge was in more than just those seven.
As the St. Louis Post-Dispatch reports, Martin conceded the race today in an email to supporters:
"In light of this new information, the implausibility factor evaporates along with my concerns about voter fraud in that late surge," Martin wrote. "And, although I have concerns about other incidents and improper conduct on election day, I no longer believe these concerns are sufficient to continue our review of what has occurred or delay agreeing that this election is over."
