Thanks to the writer of the August 22nd letter. Yes! Samples can be flawed. Studies can be flawed. Surveys can be flawed, too. Results of surveys can be flawed by whom you ask. If you want a certain answer, you ask a certain population. If the sample is only Republicans or only Democrats, the results will definitely differ. One of the first things taught in statistics is that many studies are flawed.
