But for a larger number of voters, there exists some extra resistance to voting for someone who, on the surface, seems different. This is race (or other demographic) consciousness, but not straight-out bigotry. For these voters, they need more evidence to convince them that this seemingly "different" kind of person is, under the surface, pretty much the same as the voter.

For Hillary, being a woman was a resistance factor for some. Some people think that women are less likely to be able to deal with military matters, foreign policy, etc. Hillary smartly decided to confront that resistance by going on the Armed Services Committee in the Senate to prove to the doubters that she was as tough and able to deal with such matters as the toughest men. On that count, she succeeded. Her candidacy has failed (probably) for many other reasons, but not because of her demographic "disadvantage."

For Obama, as voters are starting to look for evidence either to confirm or to refute their early suspicion of "otherness," he has offered mixed evidence. Personally, the way he carries himself and speaks, his calm reasonableness, his admirable wit and charm have worked to his favor. But his associations, his San Francisco statement, his wife's seeming anger at America tend to confirm for some that he is in fact not a sufficiently typical American. These might be factors even if Obama were Anglo-Saxon. But it is foolish to deny that the suspicions are more focused because of his race. On the other hand, it is not all race. For example, if Colin Powell were running, his lifetime of famous and gallant military and high government service would lower the resistance factor that the lesser-known and lesser-accomplished Obama is facing.

The next test for him is to avoid having his policy proposals seem so radical (almost in a European semi-socialist way) that he will be seen as "other" not only by genetics but also by philosophy. For Obama, radical policy will be even more electorally dangerous than it was for George McGovern.

Let's have an honest conversation -- with neither rankle nor euphemism.
