Here's Trump in 2012 talking about Romney.
"The amendment that I introduced removed the path to citizenship, but it did not change the underlying work permit from the Gang of Eight," he said during a recent visit to El Paso. Mr. Cruz also noted that he had not called for deportation or, as Mitt Romney famously advocated, self-deportation."

Unlike Trump, Cruz has NOT changed position. Cruz STILL defines amnesty as "a pathway to citizenship." He does not consider granting legal status to be amnesty. Cruz as of July refused to say he would deport anyone, stating that there would be a "conversation" about what to do about the people already here AFTER he is elected.
