Hispanic vote in Georgia and Oklahoma

[PGSable]

According to CNN's exit poll data, Bush only won the Hispanic vote in three states: Florida, Georgia, and Oklahoma. Florida makes sense (the Cuban vote). But Bush won Georgia Hispanics by 13%, and Oklahoma Hispanics by 48% (while winning Oklahoma whites by "only" 42%).

Is there any reason for this, besides the high margin of error for small subsamples (4% in both Georgia and Oklahoma)?

Thanks. I thought there might have been something more to it.
