Look around...
Obama has been a spectacular glorious success.
Just depends on the meaning of success...
He absolutely has been a stunning success for anyone hoping he would fundamentally change this country. Congrats.
As far as Biden, I think the guy is unelectable. If Hillary implodes and he takes the reigns, it will be the best chance pubs have to take back the WH.
Once the dust settles from his grand entrance, America will realize that Biden is a 3rd Obama term. That in combination with the fact that he’s a walking, talking, gaffe machine and makes Trump look like Shakespeare, is gonna make it pretty tough for him.
