A personal interest of mine is reading about old elections - for whatever reason, I think they're really interesting! Anyway, when I was reading 

 about Carter wanting Biden to give his eulogy, it stated that Biden was "the first elected official outside of Georgia to endorse Carter's [1976] run for president". That's kinda wild! Naturally, I wanted to find more details about it. 

I found some info, but I could not find what I was really looking for, a long article discussing the full circumstances and reasoning behind Biden's endorsement, its effect if any on the dark horse Carter campaign and Biden's reputation at the time, and maybe some not-really-justified commentary about how this may have led to Biden's rise fifty years later. Alas.

I'm hoping the market can find me some answers! To make this more specific, I've written 7 questions (well, 6 questions and a bonus challenge) I'm curious about. Resolves to the number of these questions which I feel I have satisfactory answers to by market close (at 6pm PDT on Sat., April 15, in about a month - I'm experimenting with midday close times). Some of these should be relatively easy, while some may take more digging or even creativity. I will only give points for an answer that satisfies my curiosity on that question.

 all have nothing to say about it. I did find a bit of info: 

 says it was March 25, 1976 when Biden went to Wisconsin to campaign for Carter. It includes this Biden quote: "Some of my colleagues in the Senate thought it was youthful exuberance ... I was exuberant, but as I said then, Jimmy’s not just a bright smile. He can win and he can appeal to more segments of the population than any other person. ... Gov. Carter proved me right."

, that date was after a lot of primaries, so Carter would've been the frontrunner then, and presumably Biden actually made the endorsement prior to March 25 if he was the first elected official outside Georgia.

, which doesn't discuss the endorsement directly but does suggest that Biden learned the importance of politicking from Carter, and also sought to distance himself from Carter fairly soon after he was inaugurated: "'The president is learning, but not fast enough', he [Biden] said in 1977. 'Nixon had his enemies list and President Carter has his friends list. I guess I’m on his friends list, and I don’t know which is worse.'" 

Anyway, that's all I got. I'm excited for what this market turns up!

General policy for my markets: In the rare event of a conflict between my resolution criteria and the agreed-upon common-sense spirit of the market, I may resolve it according to the market's spirit or N/A, probably after discussion.
