Scripting Games 2008 Advanced Windows PowerShell Event 3

My Answer for Scripting Games 2008 Advanced Windows PowerShell Event 3 :

$votes = gc c:\scripts\votes.txt |% {,($_.Split(','))}
While ($true) {
  $round = ($votes |% {$_[0]} | group | sort -desc count)
  #$round ; "------"
  if ($round[0].count -gt 600) {"The winner is {0} with {1:n2} % of the vote" -f $round[0].name,($round[0].count / 12);return}
  foreach ($i in 0..($votes.count -1)) {
    $votes[$i] = $votes[$i] |? {$_ -ne $round[-1].name}
  }
}

Result, *Update* updated script to completly remove candidate, to avoid confusion ;-) 

PoSH> c:\scripts\event3.ps1                                                                                             
The winner is Pilar Ackerman with 50.17 % of the vote

Can see I commented out a line, un comment it to show the intermediate  results :
