“…Pre-election violence can increase the odds of victory of its instigator through the polarization of the electorate ( Dercon & Gutiérrez-Romero, 2012 ; Horowitz, 2001 ; Wilkinson, 2004 ) and the demobilization of his opponent’s voters by means of intimidation, displacement, and death ( Bratton, 2008 ; Collier & Vicente, 2014 ; Klopp, 2001 ; Steele, 2011 ). 2 It not only affects nationwide official elections, but also intraparty contests ( Goldring & Wahman, 2018 ; Bech Seeberg, Wahman & Skaaning, 2018 ; Reeder & Seeberg, 2018 ).
