Md. voters deciding on "Dream Act" law About a dozen other states have laws or policies that echo Maryland's version. But the outcome of the referendum, Question 4 on the ballot, could set a precedent. No other state has approved such a law through a popular vote. Pre-election polling on Question 4 showed broad support for the law, which grants in-state public tuition rates to certain undocumented immigrants who attended Maryland high schools for at least three years and meet other conditions. Francisco Javier Mercado, 42, a Silver Spring resident and native of El Salvador, said the prominence of immigration issues led him to vote Tuesday for the first time. "I am 100 percent in favor of the Dream Act," Mercado said. It is another opportunity for the students that want to better themselves. We can't deny them an education. In Upper Marlboro, Sandra Bossard, 62, said she voted against the referendum. "I know young people who are citizens who have difficulty getting into college," Bossard said. We need to support our own and take care of our own. Under the law, students who qualify for the tuition benefit must first attend community college. Those who receive an associate degree or at least 60 credits at the two-year school can then qualify for a tuition discount at a four-year university. For students from families of modest means, the subsidy is crucial to hopes of getting a bachelor's degree. At the University of Maryland in College Park, in-state tuition is $7,175 a year. For out-of-state students, it is $25,554. Maryland's law stands out for another reason: Experts say no other state that provides an in-state discount for undocumented immigrants requires the students to attend community college first. The campaign on Question 4 was largely overshadowed by debate on ballot measures related to same-sex marriage and gambling. Critics of the tuition subsidy said that it amounted to a giveaway of taxpayer funding that Maryland could not afford. Supporters said Maryland had a vested interest in providing educational access, at a low price, to all its high school graduates. Some analysts estimated that the tuition subsidy could cost taxpayers $3.5 million a year. But there is little consensus on the cost because it is unknown how many students would qualify for the benefit. Debate over tuition benefits for illegal immigrants arose in the Republican presidential primary. Texas Gov. Rick Perry, a supporter of such benefits, drew criticism for his stance from former Massachusetts governor Mitt Romney, the eventual Republican nominee. In Maryland, Republican state lawmakers spearheaded opposition to the Dream Act. Neil C. Parrott (R-Washington) said the law would leave fewer slots available at U-Md. and other selective public schools for U.S. citizens. Proponents called that argument unfounded. President Wallace D. Loh, a supporter of the law, said the number of undocumented students who would qualify for the benefit at College Park would be minimal, perhaps 20 a year. "Yes, they are undocumented," Loh said. But we're talking about people who came here as children. He called the issue a matter of "fairness and justice." Lynh Bui contributed to this report.
