|I have lost count now||2 (20%)|
Well, I voted four times, for each possible answer.
Assuming the additional votes for 'twice' and 'I have lost count now' are separate people, that leaves a grand total of 2 people, or 40% of respondents who only voted once, hopefully because they were unable to vote more times. (If they just chose not to vote more times, they weren't really getting into the spirit of things.)
I look forward to the day when general elections are resolved using a blogspot poll widget.
