2. White people may vote for Obama because he's a good candidate and black, but I don't think you can say white people would just vote for any black candidate (Jesse Jackson in the 1980's) or that white people may vote for him simply because he is black. That's pretty ridiculous. At most, Barack has an advantage in that he is the first black candidate many white people can feel comfortable voting for (ie. he's like them), which is why people keep tossing around this idea that Obama is a transcendent candidate who transcends the normal racial divide.
Shouldn't white and black candidates both try to appeal to voters outside their race? I welcome the day when such issues of race are acknowledged and yet set aside for more important considerations.
