RIVERSIDE -- Latino activists began a renewed push Tuesday night for a comprehensive overhaul of the nation s immigration policies.

The Riverside-based National Alliance for Human Rights urged Congress to move swiftly to reform immigration laws in the wake of last week s election.

"With the House and Senate being taken over by Democrats, I m very optimistic that President Bush will accept and support a guest-worker program that will include a legalization component, said Gil Navarro, a 64-year-old San Bernardino resident.

About 50 members of the alliance gathered at Zacatecas Restaurant to formulate strategies for legalizing the country s estimated 12 million illegal immigrants.

The group called on Rep. Joe Baca, D-San Bernardino, to become more vocal in his support of immigration reform.

Baca, who has served in Congress since 1999, could become chairman of the Congressional Hispanic Caucus a post that would increase his clout in shaping the immigration debate in the House of Representatives.

Baca has expressed support for legislation that would provide a path to citizenship for undocumented workers.

He voted against a bill approved by Congress and signed by President Bush last month that authorizes 700 new miles of fencing on the U.S.-Mexico border.

"If Joe Baca becomes the next chair, I m confident he s going to open some doors that will allow major changes in immigration policy to take place, said Armando Navarro, coordinator of the alliance and an ethnic studies professor at UC Riverside.
