Brazilians head to polls for presidential run-off election

Brazilians take to the polls again this Sunday for the second and final round of the Presidential elections. Worker’s party candidate, Dilma Rousseff leads conservative candidate Jose Serra in the polls. But it has not been an easy campaign.  The second round debate has centered on abortion, religion, scandals, and a mainstream media campaign against the left-wing front-runner. Mike Fox has more from Porto Alegre, Brazil.
