A more important thing to remember is that the 31 percent of Hispanics who voted for Prop 187 is basically equivalent to the percentage of Hispanics in California who vote for the GOP. In 1990, Wilson won 33 percent of the Hispanic vote in his successful first bid for governor. Additionally, during the presidential elections of the 1980s, Republican candidates never performed particularly well among Hispanics in the state, with George . Bush only earning 25 percent of the Hispanic vote in 1992. In 2012, Mitt Romney won 27 percent of the Hispanic vote.
In the early 20th century, Bertrand Russell gave a different complete axiomatization of propositional logic, considered on its own, in his 1906 paper "The Theory of Implication", and later, along with A. N. Whitehead, produced another axiomatization using disjunction and negation as primitives in the 1910 work Principia Mathematica . Proof of the possibility of defining all truth functional operators in virtue of a single binary operator was first published by American logician H. M. Sheffer in 1913, though American logician C. S. Peirce (1839-1914) seems have discovered this decades earlier. In 1917, French logician Jean Nicod discovered that it was possible to axiomatize propositional logic using the Sheffer stroke and only a single axiom schema and single inference rule.
