I work with a guy whose wife called all the landscaping businesses in town to find one that didn't employ non-english speaking employees. She had to make quite a few phone calls, but she finally found one and hired him and his crew to mow their lawn.
On the other hand, I've never thought it was a good idea to inject your politics into your business unless your business was politics. You risk alienating (pardon the pun) english-speaking hispanics and, of course, the perpetually-offended Americans (liberals). It all depends on how much you need their money.
