What the hell is going on here!? One day Clinton is up by 42 in IL, next day Sanders is up by 2!? Rubio's either down by single digits in FL, or 20+ and behind Cruz. IL/NC are Safe Trump in one poll, then another shows Cruz barely behind... Pollsters have been absolutely awful in this cycle. I wouldn't be surprised if 2016 polls end up having the overall largest polling error in recent history.
Polls should report the number of people polled, so that people can do the math and calculate a weighted average. If one poll of 800 shows Sanders and Clinton tied 48-48, and a poll of 1200 shows Clinton up 58-38, you calculate a weighted average and get 54-42.
