Joe Biden missed his chance to make history at the DNC. Since his political career is finished, he could have used his time to "thank all my fellow Democrats many who I have known and worked with for many, many years for stabbing me in the back and kicking me to the curb like a piece of garbage" To all of them I say "go f--- yourselves!!!!!!!!!!!!
Many of the Kennedy family have been urging people not to vote for him, so this is his way of telling them to go f yourself, without actually saying it.
