McRae really screwed himself by putting Elissa up on the block, but like you said, he probably thought Elissa didn't stick to her plan.
It's disappointing that everybody left now is just a floater. Nobody has made any big game move with anything they have done. McRae was just Amandas's puppet, Spencer has just done what he could to stay safe, Andy is just a little weasel who goes wherever the power is.. and Judd is probably a cross between Spencer and Andy in terms of game play.
There really is nobody to root for among who is left - none of them have been "game players" like Helen, or Elissa, or Amanda.
