I have no doubt Trump and Biden could both pass these kinds of tests, as would Pelosi, Hillary Clinton, and several members of the Supreme Court. I think the problem is that when high level offices are disproportionately manned by people that old, the younger generations are not adequately represented, and neither are their values. This whole crew came of age in the 1960s, with the Vietnam War and the Civil Rights Movement shaping their views. A whole lot has happened since then. For Pete's Sake, Biden was talking about record players during the debates. I agree that we shouldn't have so many people this old in power, but how to guide them out the door is tricky.
