    Thats a perfectly reasonable sample size and margin of error. The margin of error for a given confidence level and standard deviation is proportional to 1/sqrt(n) so in order to get the margin of error down from 4% points to 2% they would need to quadruple the number of people polled. However this is worthless if you cannot attribute for systematic errors with a better precision.
