Actually there's evidence, they are not saying that they didn't did the fiscal maneuver, they are saying that other governments did the same and not got impeached.
I agree with your point about the impeachment, it's a political maneuver.
We are stuck with two options (and both are bad):
1) 2 years of stagnation and political fight inside the government
2) 2 years of maybe a recover or a complete disaster
