The final two polls in that link both show her doing better. And that also overlaps with the mid May/late May/early June state polls I linked to that showed her doing better.
Sorry jfern, she was objectively polling better in the final few weeks of the race.
That's some serious cherry-picking. The last 2 have her doing 1 and 4 points better. The previous 2 have Obama doing 9 and 6 points better. The average of the May polls was a slight Obama advantage. There were some polls where she did better, and some where Obama did better, which is very different from now, where every poll shows Bernie doing better.
Even if we indulge you and accept your comically inaccurate premise, Obama had gone through Wright and bitter/cling and proven his mettle as a GE candidate.
Sanders hasn't faced 1$ worth of negative ads from both sides about how he wants to raise your taxes, take away your health care plan and the fact that he is an admirer of Fidel Castro.
P.S. And don't start me with your wild fantasies about David Brock and the "16 NEGATIVE STORIES PUBLISHED BY WASHINGTON POST".
