That be great, to see him gone.  He has become an embarrassment to them.  It would justify bringing  a centrist in for a brokered  convention.  It would tamp down the Burisma scandal. I was just thinking the same thought.  But the wiki page Q posted said its done for presidents and those the president designates.   Not guaranteed to be a state funeral since Biden was only VP.    Plus they need enough candidates in the primary to divide the delegates so that none of them get to the number needed to become the nominee requiring a brokered convention where they can bring n the real candidate.  We have multiple people who dont want to campaign who have been possible candidates in the past. Oprah, Michelle Obama and Clinton.   They all have some scandals and problems as candidates, but have a better chance then Joe Biden.  That is unless they get arrested first.  Lets hope for that.   They will kill him off after he divides the vote to allow for the brokered convention.
