You can't take a random selection of 1300 out of a (possibly non-representative) 25,000 and have the results be valid.

Well obviously if the 25,000 is not representative, the results will not be statistically significant. Duh.
But you can certainly take a random sample of 1,300 our of a representative population and get valid results. Stats 101.

Actually a sample of 1,300 out of 25,000 should give some vary valid stats. The main problem is that it is based on only those that turned in the survey. But then all polls have that problem, I have turned down pollsters a couple of times.
