Biden’s career goes back way before his 4 years as Obama’s VP. His stint with Obama has hurt his reputation. To avoid more damage to his legacy he might find himself unable to support some of Obama’s ideas in the debate, causing him to embarrass Obama to avoid further humiliating himself.
You are right. He was hand picked way back and has been groomed into the corrupt politics for a long time. It seems like every time he opens his mouth, something humiliating comes out. Hope springs eternal that he will not disappoint and will be a further drag on the inept policies of the last 4 years. I look for Ryan to be a mighty force tonight.
