I know this is considered "hackish" and delusional, but Brown losing whites is irrelevant here, he'll still win big, because of how the electorate is structured. But, if Republicans want to think their candidate is surging to a win, then that's their problem. Drudge is quite deluded.
In all reality, all this poll is is a means of making republicans think they have a chance, so they turn out in big, big numbers and, say, just barely hold Brown under 60, which would be a big accomplishment for Kashkari.
