I think the thought is that the whites will feel guilty enough to throw a couple of their votes at a hispanic candidate, and then maybe one of them will pull off a win.
I love living in this day and age where we are free of racism and we treat everyone the same regardless of their skin tone. Never grouping people into categories like white or black or hispanic, just treating everyone like a person. It's so refreshing that we've come so far that this isn't an issue.
