Colombians voted Sunday in a presidential runoff between far-right outsider Abelardo de la Espriella and leftist senator Iván Cepeda.

De la Espriella leads with Trump's backing and promises of mega prisons while Cepeda, who defines himself as a humanist, seeks to preserve the ruling coalition's social agenda.

The election could reshape Colombia's relationship with Washington as voters weigh competing visions on security and peace negotiations.
