Bloomberg ain't biased.
Newsweek have
similar numbers, a 15-point lead for Obama.
Most current polls show a smaller lead.
Any polling this far ahead isn't worth a lot in result forecasting, but it will shape the focus and location of heavy campaigning. Example - More people are identifying as Democratic than Republican, so John McCain is targeting disaffected Dems by spending more ad money in Denver than anywhere else. So it goes.
