In a nutshell, here's how Chávez got to where he is today (from
Wikipedia):
Hugo Rafael Chávez Frías (born July 28, 1954) is the President of Venezuela. A former paratroop lieutenant-colonel who led an unsuccessful coup d'état in 1992, he was elected president in 1998. A highly polarising figure in Venezuela, his presidency has seen sweeping changes throughout the country, including a new constitution, many new social programs, and a new foreign policy distancing Venezuela from the United States.
Since he was elected in 1998 on promises of helping the poor, Chávez's influence over Venezuelan politics has grown. One year after a majority of Venezuelans voted to keep him in office, the populist leader has consolidated his power, striking a harsh anti-USA tone. He is up for re-election in 2006, and recent polls suggest he has about 70 percent popularity.
Chávez and his administration have been opposed through confrontational methods by some established sectors in Venezuela, including the business federation Fedecámaras and union federation CTV, resulting in a coup d'état, general strike/lockout, and recall referendum, all of which failed to remove him from office. Although the opposition charged that there was widespread fraud in the recall vote, international observers said the official results matched their counts at polling sites. Subsequently Chávez and his allies have won consistent political victories, occupying the vast majority of elected municipal, state, and national posts, as well as majorities in the supreme court, national electoral council and national assembly.
Chávez has been married twice and is currently separated from his second wife, Marisabel Rodríguez de Chávez. He has four children: Rosa Virginia, María Gabriela, Hugo Rafael and Rosinés.
