From an election integrity point of view Obama beating McCain and Romney is totally believable. Those guys were trash.  If youre low information there wasnt too much you could say bad about Obama.  His economy was mediocre but not sinking, Obama care was shit for the country, but it helped a lot of people in his base.  He wasnt offensive to listen to, and there were no sketchy pics of him sniffing women and children.  He didnt have any major scandals going into office other than his political views, but he largely kept those under wraps when he spoke.  Because he was a good politician, unlike Hillary and Biden.  The fraud is obvious now, if it was happening back then, it wasnt as obvious, wide spread, and they had a relatable guy that could actually talk spearheading the show.    Biden beating Trump makes zero sense.
