I would be fine if Biden, Warren, Sanders, or essentially any of our canidates gets the nomination

I think that is the way the overwhelming majority of Democrats feel. I have some preferences regarding some policies and priorities. In a more typical election cycle that would matter more to me than it does now. I don't care who has or does not have annoying traits, I am not guided by who has or does not have disagreeable followers (or bots impersonating disagreeable followers). I do however care about who has a solid chance of beating Trump. Of our currently leading candidates I am least confident that Buttigieg does, although he does impress me as a person with a very bright future.

In other words, my personal preferences remain soft. I will fall in strongly behind our candidate for President whoever that is. No hard feelings about anything will stand in the way of that for me.
