The closely contested June 21 runoff between right-wing candidate Abelardo de la Espriella and left-wing candidate Iván Cepeda has sustained high public engagement following the May 31 first round, where turnout reached a record 57.89% of registered voters. Polarization between the two finalists, combined with coalition-building efforts and mobilization of the substantial abstainer pool from the initial vote, supports expectations that participation will rise modestly into the low-to-mid 60% range. Recent polling and campaign activity show both sides focusing on turnout operations in key regions, while the absence of major disruptions or legal challenges since the first round has preserved momentum. The 60-64% bracket leads market pricing because it aligns with historical patterns in Colombia's polarized runoffs and the visible intensity of current voter outreach, whereas lower ranges reflect the possibility that fatigue or logistical factors could limit gains over the first-round baseline.
