Polls come and go but one thing is certain.
Biden is a dead man walking. If nominated the corruption reality will surface to knock him off.
If that fact were to surface before the nomination Biden would not be nominated.
Might have been the plan all along... Biden wins the primaries and then gets taken out by scandal and bingo! We have a brokered convention. No wonder Hitlery is trying to sabotage Bernie now that the news is out prematurely.
