A few people have pointed out the second numbers are actually an extrapolation of the poll data — NBC/WSJ took the poll, assumed 70% of Sanders voters would vote for Hillary, and presented those numbers. Not wording this correctly was my oversight, so here is the correction. Personally, I think 70% is a conservative number, but it’s close enough to illustrate the point: Hillary is not the weak, deeply unpopular candidate she is portrayed as being in some quarters. Her “weak” poll numbers at this point are largely a product of Bernie still being in the race, while Trump has the GOP side all to himself, along with one other factor which there is no point in exploring at this late stage of the primary.
