He also praised the anti-illegal immigration efforts of Kansas Secretary of State Kris Kobach, a law professor who had drafted much of Arizona's SB 1070 immigration enforcement law and similar measures around the country. Campaigning with Kobach in January 2012, Romney said, "We need more conservative leaders like Kris willing to stand up for the rule of law. With Kris on the team, I look forward to working with him to take forceful steps to curtail illegal immigration and to support states like South Carolina and Arizona that are stepping forward to address this problem." When the Supreme Court struck down parts of Arizona's SB 1070 in June 2012, a Romney campaign spokesman said that Romney supports the rights of states to make their own immigration laws when the federal government has failed to address illegal immigration. To help combat illegal immigration across the border with Mexico, Romney has said that the U.S. must erect a fence along the entire 2,600 mile border, equipped with technology to detect attempts to breach the barrier, and outfitted with adequate numbers of border patrol agents. Romney's positions were given mixed reactions and ratings by anti-immigration groups. Numbers USA gave him a D grade for his positions in 2011 and a 64% score in his 2012 campaign. ProEnglish, which seeks to make English the official language of the United States, gave Romney an overall 73% grade. Romney also said during the primary campaign that he would seek to make the U.S. a much less hospitable place for undocumented immigrants by eliminating what he called the magnets that attract them. An example of a magnet, he said, would be offering to undocumented immigrants the same tuition discounts that are offered to legal residents who attend public colleges in their states, a benefit that rival candidate Governor Rick Perry supported for Texas students who had been brought as children to the U.S. by their undocumented immigrant parents. Romney similarly said that he opposed all forms of amnesty because he regards amnesty as another magnet for illegal immigration. He vowed that as president he would veto the DREAM Act (legislation which would allow individuals who had been brought to the U.S. as children when their families immigrated illegally an opportunity to qualify for permanent residency if they met certain qualifications), because he considered it yet another magnet for illegal immigration. Romney has argued that a key step
