I think in this article they only mentioned Blacks, Woman, and the Young is beacause those were the top three groups who had the disability of not being able to vote back then. I do agree that he could have mentioned other race's in the article. There are many other races in America that did play a big role on voting. Such as the Hispanic/Latino race. In the following article, "In key states,Latino vote fueled Obama's Victory".

It mentioned how much of an impact the Hispanic race had on voting.

"When they turned out in record numbers to vote for Democrat Barack Obama, they not only erased recent gains by Republicans but shattered the myth of a black-Latino divide."

In the article they also mentioned that Obama won 57 percent of the Hispanic votes in florida compared to McCains 42 percent.
