Continuing a 93-year fight to control immigration, American Legion leaders are rallying military veterans to convince California voters they should require police to enforce federal immigration law.

“This country is for people who are here legally, who are born here, not for people who came here illegally, who kind of snuck in,” said Bill Siler, adjutant of California’s American Legion branch.

The Concord resident is co-sponsoring an initiative to keep it that way and plans to enlist help from the 88,780 Legionnaires statewide to help collect the more than half-million signatures needed to put it on the November ballot.

Although better known for its veteran advocacy, devotion to flag etiquette, baseball leagues and patriotic youth programs, the American Legion has lobbied for stricter immigration rules since its founding after World War I.

The group in 1920 won 75 percent of the vote for its first California proposition, strengthening state laws denying Japanese immigrants the right to own land.

The Legion then helped persuade Congress to pass national immigration quotas in 1924 and has sought immigration moratoriums and heightened enforcement every decade since.

“The American Legion, since its inception in 1919, has expressed concern that legal and illegal immigrants arriving in this country in large numbers would be unable to effectively assimilate into our society unless numerical quotas were established and enforced,” began one of five immigration-related resolutions the group passed at its 2010 national convention.

This latest California volley aims, in part, to block liberal Bay Area counties from interfering with federal immigration prerogatives. It would require all counties to fully enforce Secure Communities, the network that alerts immigration agents whenever police book a deportable immigrant at a city or county jail.

“If they go to jail, it takes our taxpayer money to keep them here,” Siler said. “If they are here illegally, they should be deported.”

The measure would also deny driver’s licenses to undocumented immigrants, which is already California law but in danger, according to proponents. And it would order sheriffs of the 20 counties with the worst cross-border gang activity to devote more resources to immigration enforcement.

Hundreds of the veterans voted to support it at their state convention in June.

“Hopefully they’ll be the ones to get out the signatures to get it on the ballot,” Siler said.

If not, “I guess that will be the end of it.”

Initiative author and co-sponsor Ted Hilton of San Diego has been drafting immigration control ballot measures since the early 1990s.

Voters have not been supportive of such drives in recent years.

Hilton’s 2009 proposal to revoke automatic citizenship for the U.S.-born children of illegal immigrants failed to find enough signatures.

A Belmont Republican’s 2010 initiative modeled on Arizona’s immigration crackdown found too few voters willing to put it on the ballot.
