This is no surprise. I live on the border in SoCal, and I can guarantee you the Latins who are in the USA legally, as green card holders or naturalized citizens, absolutely do *not* want the tsunami of illegal aliens to continue. Many are self employed or small business owners, and they constantly are being undercut by the cheap labor express.
So do I (10 miles north of it) and we're swarming with Mexicans.
