If you go to the St Lucie Board of Election http://www.slcelections.com/
you will see the link to the Election summary report http://www.slcelections.com/Pdf%20Docs/2012%2...
below the link is this note
note*- turnout percentages will show over 100% due to a two page ballot. not all voters voted the second card containing the amendments
If you go to the link you can see number of registered voters, 175554; the number of CARDS cast, 247383; and a %, 140.92%.
In an election with one card, you would divide the number of cards by the number of registered voters to get the % of turnout.
That would give a useful piece of information.
Remember that there are so many things on the ballot, that everyone got TWO cards
In this case if you take the number of cards and divide by the number of registered voters you get 140.92%, a crazy figure, not related to turnout, but labeled as turnout.
If you look further you can find an estimate of the real turnout.
Voters cast 123301 countable votes for President.
Add the votes that could not be counted: 407 blanks and the 42 who over voted you get 123750.
That would be the number of FIRST cards cast.
123750 first cards divided by 175554 registered voters or 70.49% turnout by the normal definition.
Since each voter got TWO CARDS, the number for First cards multiplied by 2 would be potentially 247500 CARDS.
This is more than the 247383 cards listed as some did not vote the second card.
Clearly the 140.92% came from counting CARDS (2 per voter), not from counting voters.
The problem here is a gross misuse of the word turnout, not gross voter fraud.
