What is the prediction on the Machusetts Senate race?

I can't find a consistancy on the polling, some say Coakley is up by 15 some say she's up by like 2 one says she's losing by 1. I'm a little lost on this one, it's a heavily Democratic state so I initially thought she would easily win, but watching Coakley in a debate I realised she's a bigger twit than Palin. When I say twit, I mean she really is a TWIT!
