Latinos now view immigration as their leading concern along with the economy in what activists say is a major shift most likely driven by controversy over Arizona’s tough law against illegal immigrants.

Nearly a third of Latinos also believe that racism and prejudice are the central issue in the immigration debate, over national security, job competition and costs of public services for illegal immigrants, according to a national survey released Wednesday…

The poll found that the vast majority of those surveyed strongly opposed the new Arizona law and strongly supported an immigration policy overhaul providing for a path to citizenship for illegal immigrants and deportation of felons. Republican Latinos showed similar views on these issues as Democrats and independents.
