Hillary vs. Obama

Finally Hillary Clinton wins back her campaign in Ohio and Texas yesterday.

I think none of them would stand chance to become the President of United States, but I am still interested in following the election. Why? --- I wanted to figure out American people are more toleranted with a female or a black president. In another words, gender and race, which matters more?

Actually some time last week, some poll answered my question clearly--- About 12% of American people have trouble voting for a female president vs. about 6% of American people have trouble voting for a black president.

Maybe it is all because of religion --- God is portraited as a man, isn't it?
And the difference between man and woman are larger than the difference between
white and black, apparantly...
