Already struggling with weak popularity over Brazil's economic ills and a political corruption scandal, President Dilma Rousseff now must fight an impeachment effort launched by a political foe who heads Congress' lower house.<br />Speaker Eduardo Cunha opened impeachment proceedings against Rousseff on Wednesday, citing a court's finding that her administration violated fiscal responsibility laws by using money from state-run banks to fill budget gaps and pay for social programs.<br />Rousseff went on television to sharply reject Cunha's accusations, and most analysts predicted she would survive.<br />"The chances of President Rousseff being impeached aren't as big as politicians say now, despite this bold move by Cunha," said Luciano Dias, a political consultant at the Brasilia-based Analise Politica firm.<br />"They are not insignificant, but they are not huge."
