Obama Flinches on Immigration

This editorial published on the New York Times on March 24th reports the withdrawal of the Obama's administration offer to Thomas Saenz, "a highly regarded civil-rights lawyer and counsel to the mayor of Los Angeles, to run the Justice Department’s civil rights division."

Although it might have been a missed opportunity to set some record about the Obama's administration intentions regarding immigration, it seems that a more moderate route was preferred by nominating Thomas Perez, Labor Secretary from Maryland. The decision, according to the article, was caused by pressure from the right-wing anti-immigrant groups. However, I wonder how much the decision was influenced by the Mexican border situation and Thomas relationship with controversial Los Angeles mayor Antonio Villaraigosa. And the main question: Does Obama need to start yet another fire?
