[M]any Latino voters don’t want to vote for Obama, not because they know Hillary better or because they are grateful to President Clinton for rescuing Mexico during the "Tequila crisis" of 1994 (Dick Morris’ explanation) but because … well, they don’t much like African-Americans**
…**–Sorry, I forgot to use a euphemism. I meant to say that there is a "history of often uneasy … relations" because of "conflicts over local resources"!
There’s a ton of talk about racism but in America it usually comes down to relations between blacks and other groups. It’s my perception that tens of millions of Americans — be they white or brown or yellow — don’t like black people (and most of these dislikers vote Republican, to quote John Derbyshire). I don’t think that most of these racists do anything significant to harm blacks but they associate blacks with violent crime and try to stay far away.
