Leonardo Rodríguez Alcaine

Leonardo Rodríguez Alcaine (May 1, 1919 – August 6, 2005) was a Mexican trade union leader and a long-serving legislator of the Institutional Revolutionary Party.

For two years he attended the National Polytechnic Institute before dropping out and enrolling at a customs officer's academy.

He climbed through the ranks and served 24 years as a PRI legislator (two terms in the Senate and four in the Chamber of Deputies).

On July 21, 1997, almost a month after his predecessor's death, Rodríguez Alcaine was elected president of the Workers' Confederation of Mexico (in Spanish: Confederación de Trabajadores de México, CTM), the largest confederation of labor unions in the country.

A day before his death, visibly weakened, he publicly endorsed Roberto Madrazo as the CTM candidate of choice for the 2006 presidential election.
