Molinar began his career as a polling representative in the
presidential elections of 1976, won by
José López Portillo unopposed. In 1987 he published an article in
Nexos magazine about
fraud in elections in
Chihuahua. He was Director of Privileges for Political Parties at the
Federal Electoral Institute (IFE) for the
1994 general election, and on 29 October 1996 he was elected IFE's Director General of the Electoral Council, a post he held until the year 2000. He shared duties with other directors like
Alonso Lujambio, Maurice Murphy,
Jacqueline Peschard,
Emilio Zebadua and the Executive President,
José Woldenberg. Between December 2000 and May 2002 he served as Undersecretary of Political Development in the Interior Ministry, where the Secretary was
Santiago Creel. He was spokesman for the
National Action Party (PAN) in January and July 2003. Later, during the 59th Legislature he was a
Federal Deputy and served as Co-ordinator for Economic Affairs of the Parliamentary Group of the National Action Party. He co-ordinated research and policy analysis during the presidential campaign of
Felipe Calderón and, once the electoral process was completed, he joined the transition team of the president-elect. Calderón appointed Molinar director of the
Mexican Social Security Institute (IMSS), relieving Fernando Flores y Perez. In April 2007 he intervened in a dispute over
abortion. Although the Federal District Legislative Assembly decriminalized abortion in
Mexico City in the first twelve weeks of gestation, Molinar declined to provide that service in the clinics of the institute he headed. This has raised criticism from some lawyers and constitutionalists. Molinar was also the director of IMSS on 5 June
2009 at the time of the
2009 Hermosillo daycare center fire in which 44 toddlers and infants were killed. ==Death==
