<p>What you are forgetting is that percentages are a useful comparison within the SAME state, when comparing between states, you also have to take into account the population (which can also be taken into account in same state comparisons as to what ranges are looked at, since if there is a large population in a state and a high cutoff, look primarily at 75-80 and ignore 70-74).</p>
