As another Brazillian, let me offer an attempt at a more distanced take on the matter. Roussef's impeachment proceedings are motivated by alleged budget manipulation. I don't think there are many who would say the maneuvers in question were 100% kosher, but the question of whether it is a sound basis for impeaching an elected president is not a simple one. Renowned legal scholars differ on this point.

In particular, it is clear the congress voted for her ousting due to a series of reasons unrelated to the allegations. One reason is the dismal state of the economy, likely due in no small part to Roussef's policy decisions. Another reason is that a majority of politicians, from all major parties, are facing serious corruption charges from a large, unprecedented, investigation conducted by the federal police, and the impeachment acts as a diversionaty tactic (there are recordings proving this is not a conspiracy theory). Lastly, there is the usual power struggle, that is fiercer and more complex in an environment with many political parties.

In all, a complex scenario that does not bode well for the immediate future of the Brazilllian democracy.
