Democratic Front Runner Joe Biden lit into a union shop steward during a campaign stop in Michigan Tuesday over questions about guns.

Biden told the man he was, “full of shit” when he was asked about taking guns. The exchange was caught on several cell phones from many different angles and is not flattering to the seventy-seven-year-old Presidential candidate, who is clearly agitated by the questions about his lack of support for the Second Amendment. Even as campaign handlers tried to pull him away from the heated confrontation, Biden pulled away and declared people should not own “AR-14’s”.

It could be the lasting impression of the Biden effort in the Michigan Primary that he is widely expected to win by a wide margin over Democratic Socialist Bernie Sanders.

It is just the latest meltdown in a series of angry outbursts involving Biden and people attending his events. At least this time he didn’t call the man a “Lying Dog Faced Pony Soldier.” So, at least, you’ve got that.

These unstable moments have many observers wondering how Biden will fare in next week’s head to head debate with Bernie Sanders or a possible future date on a debate stage with President Donald Trump. Both will put Biden in a place where his handler will not be able to intervene and keep him out of harm’s way.
