Barack Obama & Hispanic Voters: What's The Problem ?

It is no secret that Barack Obama will have a tough time getting the Latino's vote. California, Arizona, New York and others are key electoral states that he needs. What's the problem between blacks in general and Hispanics ?

Could it be that Hispanics are in America in large numbers because they are doing jobs that blacks wouldn't or couldn't do ? For any good the civil rights movement accomplished, further disconnecting responsibility from rights wasn't one of them. Hispanics value workers .
