PHOENIX AP – The debate over Arizona’s new illegal immigrant law promises to move from protest lines and talk shows to the courtroom, where a judge could be asked to decide whether the state can enforce laws that until now had been the federal government’s exclusive domain.

Opposition grew as opponents used refried beans to smear swastikas on the state Capitol, civil rights leaders and others demanded a boycott of the state, a petition drive began to put the measure to a public vote and the Obama administration weighed a possible legal challenge.
