Angry demonstrators took to Sao Paulo's streets Saturday to push for the ouster of President Dilma Rousseff, with some charging that she should be impeached.

An estimated 2,500 people marched through the country's sprawling industrial and financial hub, frustrated with her re-election to a new term amid critics' concerns about her government's alleged role in potentially allowing or enabling corruption.

Last week's vote showed huge support for the incumbent President in the impoverished northeast, where millions receive benefits from huge welfare programs Rousseff's PT has rolled out over the past decade.

The programs have helped lift out of extreme poverty some 40 million people, who formed the bedrock of Rousseff's support as she saw off business world favorite Aecio Neves.
