Good points. This is why I asked. I don't think she wants to be in politics either but if someone could convince her, she could be very unifying for the party right now regardless of whose running mate she would be. Even Republicans don't dislike her (although they tend to make fun of her school lunch program which is probably warranted. She may have had good intentions for it but that's not really what it looked like in the end). While I certainly don't think it would be smart to plan a ticket around appealing to the same Republicans who swore they were anti Trump in public and then secretly voted for him, I also don't think it hurts to have someone with broad appeal if they fit the other goals first.

Sure, she doesn't have a lot of experience. If Pete had the nomination, he had to be strategic about having a running mate with more experience than he has since that was one of the biggest concerns. This isn't quite as concerning for Biden who has a long resume and has had the benefit of saying "I was part of that" to anything good that came out of the Obama White House. Nobody is questioning his experience.

If Biden gets the nod, I agree that he needs a female running mate but in addition to that, his real goal should be someone who can heal the fractures in the party that the extreme Bernie bros are creating. Not sure if Michelle is the one best suited to do that (which is a moot point, because as we agree, she won't do it) but I do think his choice needs to be strategic around this goal. In my opinion, the biggest mistake he could make is choosing another moderate who makes the large population of democrats that like Bernie feel unheard. Despite what they say, I think most democrats will show up to vote against Trump unless the democratic nominee treats them as if their views are irrelevant.
