"But that's pretty poor compared to how many pollsters GOT IT RIGHT" -- Why do you find this meaningful?
I'll send you the updated Nate Silver rankings when they come out. That's how it is meaningful.
You can defend that statement, I suppose, (although it will have a very marginal effect) but how do you defend "After a stellar polling job in last night's Wisconsin recall (NOT)"? You have rather low confidence (probably less than ~70-75%) that's true.
"Bias" in statistics is not the same as "house effect," which matches the colloquial definition of "bias." Statistical bias is any deviation from the population parameter.
Repeatedly missing in 1 direction like they did with Amendment 1 is a sign of putting out nonsense.
1. The average systemic bias on gay marriage polls (-7) is greater than the average systemic bias on other polls, indicating it may not just be the pollster's screw-up.
2. Show me something with actual statistical analysis and I will entertain your conclusions. Otherwise, how do you not know you're accidentally cherry-picking?
