Except I'd venture it would not be a good sample as it's not necessarily very statistically representative of the whole population (ie. random)?

Of whether the people choosing the candidates have to be or even should be statistically representative of the whole population can be argued. The choice of candidates or order on ballots in many countries is decided by various less-than-representative groups.

That's pure conjecture as the article doesn't address the sample at all. It just basically says "The sample is 9%". It doesn't say why this is bad.
