World of Reel‘s Jordan Ruimy has reviewed selections from a fair number of anonymous Oscar ballots (he includes links to 13 but claims there are seven more piggy-backed or bunched in).
Ruimy reports that Penelope Cruz is the far-and-away favorite in the Best Actress realm, being the top-poller in 15 ballots (or something like that). The next closest contender, he says, is Kristen Stewart with 5 votes; Jessica Chastain has 3 votes.
Obviously this is a non-scientific count and far from comprehensive, but within this small sub-section Cruz is the hottie.
