Sure, but in the end all that's left is infinite recurrence, as has mostly been the case in latin america.
Corruption is a structural problem, rather than a political one. Sometimes it's baked into the structure (the philippines and its constitution is a very good example of this), and sometimes it's social; it's just how they folks do business in the first place, and in the context of politics what's everyday is a big no-no. It's not something that can be voted or coup'd away, else the americas would have been rid of it long ago.
