Singaporeans as it assumes that they are not able to see the value or merit of minority candidates, and only vote for candidates with whom they share a common race, culture and language. Law of large numbers Derek da Cunha has proposed that the law of large numbers favours the GRC system. According to the theory, the large number of voters from GRC wards generally, though not necessarily always, reflects the popular vote. This was evident at the 2006 elections, at which the PAP garnered an average of 67.04% of the votes in a contested GRC, while the average was 61.67% for a SMC ward. The national average for the 2006 elections was 66.6%. Similar trends can be seen from previous elections. The gap grew from 3% in 1991, and remained stable at around 5% in the 1997, 2001 and 2006 elections. This may be attributable to the enlargement of the size of GRCs in 1997 which gave greater effect to the law of large numbers.
