Just watched a small clip of Bill Clinton speaking. He looks and sounds old and frail like Biden.
But consider this:
Biden first participated in Presidential primaries 40 years ago.
When Bill Clinton was elected President, Biden had been a Senator for 20 years already.
Clinton's term ended 24 years ago and yet he is 3 years younger than Biden, who up until a couple of months ago, the media and his party kept parroting that he is "sharp as a tack" and that those who say he is senile are just conspiracy theorists.
