Only 2% of the voters in that district are Hispanic and I don't buy the 'consistent" 60% figure, do you have a source?
What about your source? The Almanac of America Politics 2006 shows people of Hispanic Origin” at 13.7%. I mean come on, this is San Diego. Right next to the Southern Border. There’s no way in hell, even intellectually, that Hispanics would only number 2%.
My source is an old interview with Duncan Hunter in the Presidential Election. That is reflected here.
