I’m thinkin there are unlimited photos and videos out there of Joe “hands on/shotgun” Biden. Pretty sure I read someplace he never got how to take advantage of the DC gravy train.
Irrelevant. He’ll get endless top cover from the MSM on those issues.
If they believe Biden is their best shot at taking Trump down they're run Biden.
Whether he can win or not will depend on many, many news events between now and 2020 that have yet to happen.
