so,

1) there is no actual evidence that biden is fading.
2) while i acknowledge that she is doing very, very well with her own specific demographic, i still don't think that warren actually has a serious path to the nomination.
3) i still think that sanders' only real path to beating biden was to rely on splitting the vote in the south, and running up the score in the north and west - something i don't think warren can actually do. sanders cannot displace biden as the christian conservative candidate in the south, although warren perhaps could if she were to run in a certain way, and the idea that he ever could was always stupid. so, i still think that sanders is being badly blocked by biden, and that, while there are some things he could do to try to get around him, he's not doing them - he's instead trying to fight a losing battle head-to-head. the south is just a conservative place.
4) i still think that booker is the most realistic dark horse, although i pointed out a while back that there may be a class disconnect between himself and his intended voting base, that they may actually not see much of themselves in him at all.
5) harris is terrible. she's fading.

the others were never really serious candidates.
