Poll: Sharp drop in Brazilian president's approval rating amid inflation fears

A new poll shows Brazilian President Dilma Rousseff has suffered her biggest drop in popularity since she took office in 2011.

The Datafolha survey finds 57 percent of respondents giving positive marks to Rousseff's government, down from 65 percent in March. Her government received a negative rating from 9 percent of respondents, with the rest giving the government a regular rating or not responding.

About half of those surveyed said they were worried about inflation, while 36 percent said they had unemployment concerns, both up from the March survey.

Still, the poll showed Rousseff would easily win re-election against former Environment Minister Marina Silva, opposition Sen. Aecio Neves and Pernambuco Gov. Eduardo Campos.

The poll surveyed 3,758 people on June 6 and 7 and has a margin of error of 2 percentage points.
