Never did understand the "Margin of Error" thing. If you call 100 people & ask who their choice is for president and they all give an answer, shouldn't the margin of error be zero?
If the margin of error is 4%, it means that there is a statistical 95% confidence that the poll result from the sample is within 4% of the actual result if you were to poll 100% of the entire target population. The MoE is inversely related to the sample size. Also, the MoE starts with the assumption that the poll sample is a representative demographic crossection of the overall target population. So, criticism about the polling methodology or demographic assumptions is a separate thing entirely from criticizing the MoE which again is mostly just dependent on the sample size.
