PUMA's and the Electoral College

There are several scenarios given the states that are in play where we could have an electoral college tie or a win by Obama by just a vote or two.

Given the nature who the electors are (long-time party donors and loyalists), and the fact that under the Constitution they are free agents (though some states make them sign pledges), do you suppose there are any PUMA’s among the Democratic slates of electors? Perhaps 1 or 2 among New York’s 31 electors? Anyone see where I am going with this? Am I crazy?
