The term began to be used by conservative and moderate Republican presidents beginning with Richard Nixon in 1968 when he was running for election. His pledge was to appoint justices that interpret the law and reinstate "law and order" to the judiciary. President Nixon appointed four justices that seemed (at the time) to be of that philosophy. One of them, Harry Blackmun, however, shifted leftward, while another, Lewis F. Powell, became a moderate. The other two were in the mold of what most think of in terms of strict constructionists. Gerald Ford, when running to serve a full term of his own distanced himself from this issue. Ronald Reagan, however, also promised "Strict Constructionists". All three of his US Supreme Court nominees loosely fell into this category. Still one was more of an originalist while the other two were fairly conservative. Since Reagan, Republican presidents George W. Bush and Donald Trump, along with Republican nominees John McCain and Mitt Romney, have all promised to nominate strict constructionist judges to the courts.
