For reference (going back to the WSJ thing I posted) Obama had 90% of Black voters and barely beat her, primarily because he campaigned like crazy in rural areas to help w/ his margins there because of the proportional nature of the Dem primary setup.No it wasn't. It was virtually impossible for Sanders to win against Clinton as late as the end of March.

The only reason the contest APPEARS to have been anywhere near close is because despite the impossibility of actually winning against Clinton by getting more votes, Sanders continued to run long after the point that wasn't possible with the rationale that superdelegates should support him anyway as the superior candidate.
This is an insane strategy that had no chance of working, and any other primary candidate would have dropped out as soon as a win was out of the question. Sanders of course continued to run an impossible campaign that did nothing but rack up votes that made the election appear closer than it actually was.
Again, no other democratic or republican candidate has done this EVER- because it's nonsensical, wastes money, and damages the presumptive nominee. Sanders of course didn't care.
Not being willing/able to campaign in "unfriendly territory" was a problem with both Sanders and Clinton in 2016 and we deserve a candidate who actually understands that part of the gig.
