Reply #2: CNN-International did a report on how this year might be the opposite effect

They pointed out that Obama did a lot better in many primary states than polling showed.

That is many small midwestern and southern towns where there is still overt racism, people who are voting for Obama won't say so openly, but will in the privacy of a voting booth.

It was a very interesting segment.
I'm assuming it made it to CNN in the USA
