Also, what kind of Common Core Math gives Biden a +8 advantage over Bernie in the primary, but has Biden losing to Trump and Bernie beating Trump? I can't think of how you could even cherry pick a sample to get results like that.
If Biden's advantage is not about actually liking the candidate, but about falsely perceived electability, that would produce these numbers. You would also see these numbers if Biden was really strong among Democratic loyalists who will vote no matter what, but Sanders was stronger among the left, young voters, and independents.
Good thing that's not the case, right? Biden's definitely gonna win?
