in the case of Crossroads and similar groups running massive ad campaigns on his behalf, while tearing down Hillary. Hillary is likely at the lowest she would get barring a disaster while Bernie is as high as he could get barring a GOP collapse. With that they are not that far apart. Sanders has zero, zero chance of winning any state south of the Mason Dixon line that isn't Maryland. Hillary has a good shot at Florida and Virginia. Sanders might drive up turnout in states we already do well in but that does us no good. I agree with the several responses that say the polls would have meaning after nomination.
