Printing unlimited money, supporting cuban dictatorship with oil billions, digging deeper in social division and looting public treasure... you can believe in whatever society model you want, but persistence in error to the point of leading the country to misery is irresponsible.
My point is, from the perspective of an average voter, replacing a corrupt bunch with another corrupt bunch is a pointless exercise, so might as well send in the strongman. That's pretty much the standard scenario in which democracy dies (Weimar, fascist Italy, II French Republic, all the way back to Julius Caesar).
If the new one just don't destroy the economy, or recover from inflation / unemployment, it has done more good than the previous one.
For a lot of people, Chávez was a measurable improvement over his predecessors.
