Analysts describe Lula, 80, as the underdog, with his only path being to turn out non-voters — historically unprecedented. Experts attribute his vulnerability to antiestablishment sentiment, his establishment status, and a shift toward social and religious issues, despite economic gains. Both candidates carry high negatives.
