Presidential candidate Dilma Rousseff has strong lead in recent polls heading into Sunday's run-off election. Here are the details.

Brazilians head to the polls to choose a new president in Sunday's run-off election.

Ruling party candidate Dilma Rousseff led opponent Jose Serra by double digits in recent polls.

If elected, she will be Brazil's first female president.

Popular at home, she's also finding support from across the world.

Residents of Gabrovo, Bulgaria where her father was born, are proudly celebrating the daughter of one of their own.

[Markova, Gabrovo Technical University Chancellor]:
"We are proud here, that Dilma Rousseff is a descendent of Gabrovo and she is so popular in her country. We hope that she will win the second round of presidential elections and become the first woman president with origins from Gabrovo."

President Luiz Inacio Lula da Silva hand-picked Rousseff, his former energy minister and chief of staff, to succeed him.

She faced off against opposition candidate Serra in their final debate Friday.

[Dilma Rousseff, Brazilian Presidential Candidate]:
"The president of the republic must deal with the real and concrete lives of the people and not with number(s) and abstract entities that don't have to do with the daily life nor experiences each Brazilian lives through."

The run-off election Sunday comes after Rousseff fell short of winning the majority of votes needed in the initial October 3 election.
