If Maddy can take herself off the block then I think there's a chance that Jared will be backdoored.
The bros like Ramsey and want him to stay and have expressed this. They think he will align with them so why would they get rid of him? I think it would be a relatively easy sell to get Jared up, which Tim may push for if he thinks he or Nikki might be pawned. I know he says he doesn't care/wants to be a pawn, but I think it's a front to appear less threatening.
So, yeah, I'm cheering on Maddy to win the Veto.
I think it was a really dumb move on Tim's behalf to change his mind on the nominations. Mad/Ram look up to him and believe he's on their side, whereas Jared/Kels/brothers/Joel are all onto him, and his relationship with Cass is self-serving on both parts.
I think that decision has cost him the game, and it's definitely cost the brothers theirs.
