Sergio Massa is the left-wing presidential candidate in Argentina.
He promises a government of national unity and a gradual economic recovery, preserving the welfare state, central to Argentine culture.
Facing him is Javier Milei, 53, who describes himself as an anarcho-capitalist economist.
A television polemicist for two years, he says he is determined to cut down the enemy state and dollarize the economy. For him, climate change is a cycle, not the responsibility of man.
