How come you thought Biden would get it? Props for getting two out of three though!

2041-2045: Vice President Elissa Slotkin (D-MI)
Biden had in fact announced that he was running for President on the day that message was posted. Though of course he was an unlikely candidate even then (he basically sank his candidacy that same day by saying that Obama was "the first mainstream African-American who is articulate and bright and clean and a nice-looking guy").
