SAO PAULO (Reuters) - President Dilma Rousseff's approval rating sank by 27 percentage points in the last three weeks, a poll showed on Saturday in the strongest evidence yet that the recent wave of street protests sweeping Brazil poses a serious threat to her likely re-election bid next year.

The share of people who consider Rousseff's administration "great" or "good" plummeted to 30 percent from 57 percent in early June, according to a Datafolha opinion poll published in local newspaper Folha de S.Paulo.
