President Donald Trump embarked on an extended tirade against former Vice President Joe Biden on Monday night during his campaign rally in Pennsylvania, trying to use as a battering ram the fact that Biden left the state (when he was 11).

According to Politico, he accused the then around-sixth grade Biden of abandoning the Keystone State and its job development.

“He’s not from Pennsylvania,” Trump said. “I guess he was born here, but he left you folks. He left you for another state. Remember that, please….He left you for another state, and he didn’t take care of you, because he didn’t take care of your jobs. He let other countries come in and rip off America. That doesn’t happen anymore.”

Trump and his team are acutely worried about Pennsylvania, along with Michigan and Wisconsin, all places where internal polling suggests that Biden is leading the President.
