Three Questions In A Row About Race (and Gender)

Anderson Cooper protests: these aren't my questions! Dude -- yes they are! You chose them.

But race it is.

Obama, asked to respond to hypothetical charges that he isn't black enough, revived this line:

"When I'm catching a cab in Manhattan, I've given my credentials."

Hillary Clinton:

"When I'm inaugurated, it's going to send a great mesasge for a lot of little girls and boys around the world."

Edwards had something to say: "Anyone who's considering not voting for Sen. Obama because he's black or Sen. Clinton because he's a woman, I don't want their vote." Weird -- one assumes that to be the case. Is he responding to charges that his electability criticisms of Edwards and Obama are somehow raced and gender-based?
