It's becoming increasingly likely Biden drops out. And even if he doesn't, I think Scott would be more reluctant to endorse Biden in his current condition- Scott said he considers Biden senile now. He might still go "anyone but Trump" but I think it's less likely he'll openly endorse Biden.

idk, he's pretty naive about politics (to the point of being stupid) even though he's generally not stupid

I'll avoid voting in this one because I'm terrified of ambiguous resolutions (and the word "endorse" is just asking for it...), but for the record I'm surprised that the probability is above 50%.

I'm also surprised that nobody's asked how an "anything but Trump" endorsement would resolve this market! I'm open to suggestions, but I think it's reasonable to resolve YES there (assuming that it happens after Biden is the democratic nominee). Another option is to resolve PROB, based on a reasonable estimate of how many people who read the vote Biden instead of a 3rd party. (That would most likely be something like PROB 95%.)

@ScottLawrence Also note that there's an open arbitrage opportunity:

@ScottLawrence No, wait! I answered the "anybody but Trump" question already in that market! My previous answer stands, and I'm sorry for the confusion. As I said there: "No. Needs to be an endorsement of a specific candidate."

I was about to ask that question, and then read this comment.

Does a "how I filled my ballot" post where he mentions his reasoning for voting for Biden count?

@ShakedKoplewitz By itself, no. If the word used isn't "endorse", it's gotta be something phrased as a serious recommendation for how "you should" vote.
