The message blaring out of six Houston radio stations was loud and clear. "Look at all those people," says a voice. "Where do they come from?" A companion replies, "It will get worse...They want to let in millions more immigrants."

The slick radio campaign kicked off last week by the Washington-based Federation for American Immigration Reform says traffic, homelessness, drug smuggling and other social problems will only escalate if present rates of immigration continue. FAIR is seeking a tighter lid on illegal immigrants and a 300,000-a-year cap on legal new arrivals.

Outraged by FAIR's campaign, some community officials have called for a boycott of the radio stations. In the face of such protest, the stations withdrew the ads. Unfazed, FAIR is looking for other outlets.
