yeah i wish i could explain it better, but it is quite interesting. the paper may be unbiased, its that there is a problem with this method. it depends on where they poll people, what time frames they decide to use, how many people they poll, so many things that can affect the total and so many different numbers come from it that arent even close to each other. i dont like it because it can intentionally make it very low or very high to fit the purpose of the pollster.
