Are you serious? Denise, Malcolm, RC and Penner were never going to vote for her. They despised her. Carter voted for Skupin. I can't imagine Jeff voting for Abi, either.
She gets Pete and Artis' votes. That's all.
If it's Skupin, Whelchel and Abi as the final three then Abi has a better shot than the other two did with how it played out.
Abi has Pete and Artis locked. I give Jeff vote to Abi also but that's not as locked up as the other two. At least Abi has two votes which would be better than what Skupin and Whelchel got.
We will assume that both RC and Carter vote for the person they originally voted for which would be Whelchel and Skupin.
2-1-1 for Abi at this point and it's down to Denise, Malcolm, Jeff and Penner.
I agree that Denise and Malcolm don't vote for Abi. Malcolm probably votes for Skupin because Whelchel had burned him early in the post merge game. Denise could go either way, not entirely sure who she would vote for.
3-2-1 or 2-2-2 depending how things go with Denise and Malcolm voting.
Penner could decide the winner in a 3-2-1 situation if Denise, Malcolm and Penner all vote for the same person out of Skupin and Whelchel. If it's 2-2-2 before Penner votes then the worst he can do is 3-2-2. Which leaves Jeff who I believe votes for Abi and would make it 3-3-2.
So it's either a 4-3-1 win for either Skupin or Whelchel if Denise, Malcolm and Penner all vote for the same person. Otherwise it's a 3-3-2 tie between Skupin/Whelchel and Abi. Therefore Abi had a better shot at winning Survivor if she makes it than both Skupin and Whelchel did in real life.
