Fibromyalgia is a chronic illness that causes numerous symptoms, including widespread pain, intense fatigue, and muscle weakness. Few effective treatments are available to people with fibromyalgia, contributing to the great frustration caused by the illness.
A study conducted overnight found liberal-leaning pollster Public Policy Polling was the most accurate predictor of the 2012 presidential election.
A typical margin of error â a measure of the accuracy of a public opinion poll â is about 3%. In a poll that says that 52% of the respondents favor Janet Smith for Mayor, somewhere between 49% (-3) and 55% (+3) of the voters actually do support her. You can see how predicting a close election can be very difficult. Given the challenges of accurate polling of public opinion, it is amazing that polls that follow the right steps almost always make the right predictions. They've come a long way since George Gallup helped his mother-in-law win her election in 1932.
