A possible prerecorded message:
My name is Joe Biden.
It has been my great pleasure to serve the America people for over 50 years.
I wish I could continue to do so for many more years, but the pills my doctors give me are not going to allow me to do so.
Therefore, I must ask you to vote for the Biden/Whitmer ticket in the coming weeks knowing in advance that I will resign shortly after being sworn in. My vice-presidential running mate will serve you well in my stead.
I thank you for choosing me as the Democratic nominee and I will do my part to ensure a better future for you. I need you do your part by voting for me, Whitmer and other Democratic candidates.
One reason Joe might pick Whitmer is because she can easily campaign to win votes in the critical state of Michigan.
Good one.
Like the surprising night I watched TV with many others and could hardly believe LBJ said he was not going to run for re-election after all.
