[Birthright Citizenship Not Mandated by Constitution]

The leadership worries that Trump will derail the party’s plans to appeal to the Latino vote. Establishment Republicans believe that the future of the party depends on being able to capture a larger share of this rapidly expanding electorate. Trump’s plan, however, may appeal to the most rapidly expanding electorate, senior citizens, and may have an even greater appeal to the millions of Republicans who stayed away from the polls in 2012 as well as the ethnic and blue-collar Democrats who crossed party lines to vote Republican in the congressional elections of 2014. All of these voters outnumber any increase in the Latino vote that Republicans could possibly hope to gain from a population that has consistently voted Democratic by a two-thirds majority and shows little inclination to change.

Critics say that Trump’s plan is unrealistic, that it would require a constitutional amendment because the Fourteenth Amendment mandates birthright citizenship and that the Supreme Court has upheld this requirement ever since its passage in 1868. The critics are wrong. A correct understanding of the intent of the framers of the Fourteenth Amendment and legislation passed by Congress in the late 19th century and in 1923 extending citizenship to American Indians provide ample proof that Congress has constitutional power to define who is within the “jurisdiction of the United States” and therefore eligible for citizenship. Simple legislation passed by Congress and signed by the president would be constitutional under the Fourteenth Amendment. Birthright citizenship is the policy whereby the children of illegal aliens born within the geographical limits of the U.S. are entitled to American citizenship — and, as Trump says, it is a great magnet for illegal immigration. Many of Trump’s critics believe that this policy is an explicit command of the Constitution, consistent with the British common-law system. This is simply not true.
