Ten out of every eleven superdelegates don't think this matters as much as you think it does.

They actually show you the methodology.
Is this snark? The linked post is about PA turnout, poblano was wildly wrong about PA turnout. He predicted 1.6 million voters but 2.3 million showed up, he was off 28%. Now granted, in this post the day before the primary he starts wildly tweaking his models a la Zogby, but he was still off by 10%.
And BTW, can you give me a link to where he "shows the methodology" of his electoral vote projections at the top right of the page? The numbers there don't match his summary along the left and right sides of the site.
