Copacabana beach turned red for President Luiz Inacio Lula da Silva as hundreds of bikers revved their engines for right-winger Flavio Bolsonaro on Saturday on the eve of Brazil’s nail-biter election.

Tens of thousands of supporters flooded the streets as the incumbent and his rival wrapped up a bitter campaign that has left Latin America’s biggest nation more polarized than ever.

Lula, who turns 81 next week, jumped up and down on the back of a campaign truck, waving a massive Brazilian flag as he made his way through throngs of supporters wearing the red of his Workers’ Party (PT).
