It took me two seconds to do this search, and I'm sure I could find more if I wanted, but here.

I would like to point out that I cannot completely dispute what I think your basic claim is here, because I did another cursory search for Sotomayor and "white-Hispanic" and couldn't find any results. It could just be because the first fifty or so results I found were all about the case she ruled on involving white and Hispanic firemen (which in and of itself divided the two into two separate categories and didn't say white and white-Hispanic firemen), so I suppose it could be in there somewhere. I wouldn't say it is never used, but my preliminary results seem to indicate it is somewhat infrequently used. I am far too lazy to dig through the entirety of newspaper headlines to see what percentages stories about Hispanic Americans also mention their race, but I know it is at least more than zero.
