Don't trust these biased polls one bit.
Do you claim that they changed the numbers they got?
No, but I claim that they are not expert pollsters and have a reputation of liberal bias.
Let's assume that they are very liberal, how does it affect the numbers?
Let's even assume that they are poor polsters. Why in this case the numbers deviate necessarily toward Kerry in all four states.
Because they only poll in cities or do random calling or ask people at only a certain time, i don't know. All I know is that I read the Tribune, it's very biased, and they're not experienced pollsters. It's just like Strategic Vision, Zogby, other unreliable polls. Most people could agree it's Bush +2 in WI, Bush +2 in OH, Kerry +2 in IA, Kerry +2 in MN. That's fair, that seems more accurate, more logical. I don't like polling, even when it does favor the candidate I like. Because there's too many things that could go wrong or are unaccounted for. They also can discourage people from voting if the percentages are greater than 5 or 10% towards one candidate. I like the blue state, red state predictions better.
