BRASILIA, Sept 3 Brazil's ruling party
candidate Dilma Rousseff held her lead in October's
presidential race and would win in a first-round vote, an Ibope
opinion poll showed on Friday.
Rousseff garnered 51 percent voter support against 27

TV Globo did not reveal the valid vote tally on Friday.

had no impact on Rousseff's lead.
Rousseff is seen as continuing Lula's mostly

economic growth in recent years.
But she also intends to heighten the role of state
companies in several key industries such as oil, banking and

expand its majority in Congress, several analysts say her
leadership ability will be put to the test by Brazil's
