Eduardo Cunha, whom the WaPo once referred to as Brazil’s evangelical Frank Underwood has been charged:

On Thursday, Brazilian Attorney General Rodrigo Janot formally charged Eduardo Cunha, Brazil’s highest-ranking lawmaker with commanding a farrago of felonies, including shaking down suppliers of Petrobras, the scandal-ridden national oil company, for some $5 million, and then laundering the bribes through more than 100 financial operations from Montevideo to Monaco.

Mac Margolis explains:

Ever since Cunha won the right to the top microphone in Congress, trouncing Rousseff’s own candidate for the job, the Rio de Janeiro lawmaker has dedicated his mandate to making her life miserable, delaying revenue raising initiatives and planting some “fiscal bombs” in Congress that would plump constituents’ earnings at the expense of the swelling public deficit.

So how do you say schadenfreude in Portuguese? After weeks of escalating rhetoric and street protests clamoring for impeachment, suddenly it’s Rousseff’s archenemy who looks to be on the brink.

But hold those vuvuzelas. While Cunha may be hobbled by the scandal, he’s hardly out of play. Even if the Supreme Court accepts Janot’s indictment and sends Cunha to trial, he has no obligation to step aside. Removing him would take half plus one of the 513 members of Brazil’s lower house, an ecosystem where Cunha is at home.

Cunha is second in line to succeed the president. As Speaker of the lower chamber he controls the legislative agenda and the budget.

As you may recall, Cunha made The Economist last month when he announced that he would defect to the opposition without leaving the Brazilian Democratic Movement Party (PMDB),

If numbers were all that mattered, the PMDB would be the most powerful party by far. Besides having more seats in Congress than any other, it outguns its main rivals, the PT and the centre-right opposition Party of Brazilian Social Democracy (PSDB), in state and local governments (see table). The PMDB has 2.4m card-carrying members, more than the PT’s 1.6m.

In Brazil’s Byzantine political environment, the move to charge Cunha may be seen as payback for Cunha’s defection, who in turn may deny approval of Dilma’s (rather weak, if you ask me) proposals to slash government spending, raise taxes and reduce bureaucracy.

More interestingly, the question remains whether Cunha would push to impeach Dilma (as the demonstrators demand), and if he does, will Dilma gather enough congressional support to avoid impeachment – with the help of PMBD members.
