  Basede on a study of the modern presidencial democracies in South America, we
present a statistical mechanics exploration of the collective, coordinated
action of political actors in the legislative chamber that may result on the
impeachment of the executive. By representing the legislative political actors
with neurla networks, we observed that the larger the effective number of
presidential-agenda items are treated, the smaller the chances for a
cross-party dialogue, which, if combined with a decrement in the president's
public approval rating, could trigger an impeachment process.
