Guys, Bernie loses by more than Hillary. Biden loses about the same. If you weren't satisfied with progress under Obama, why in God's name do you think Biden would be any better? Two salient points against Hillary were she wasn't up to the rigors of the job and she'd been in DC for 25 years. Biden was 5 years older, fought brain cancer, and had been in DC since 1972. He also had a few minor scandals in his past that would have been blown up and has plenty of corporate ties. The same whiners who stayed home would have done the same for him. He may very well have pulled out PA since he was originally from there but that wouldn't have done the trick.
Bernie would have gotten crucified. His tax policies would have been relentlessly mocked by the so called liberal press, he looked like he was 85 years old and we would have been refighting the 1960's 10 times over. I also can't see him putting up with the withering criticism and negative campaign Trump would have sent his way. That tax snafu his wife is in also would have been front and center.
Given the laziness and instance on a cult of personality out of the left, only Obama wins that election, and he was constitutionally barred from running. Sad but true.
