The best way to respond to a basher saying that the sample size is too small is to tell them that 2,500 is a good sample size for the population according to established norms of sample proportions.
When a population is less than 10,000 then a good sample size can be 10% but if the population is above 10,000 then a sample limit of 1,000 is fine.
This is because increasing the sample will not necessarily change the accuracy if the same sampling method is used.
Seeing as the population here is 67 million which is more than 10,000, a sample of 2,500 people is more than enough.
