Parties' parliamentary attack behaviour throughout the electoral cycle

Studies examining parties' attack behaviour, also called negative campaigning, largely neglect temporal dynamics. Therefoe, this paper examines how the electoral cycle, the period between two elections, impacts parties' attack behaviour in parliaments. We argue that parties attack all the time but that the (i) level, (ii) type, and (iii) nature of attacks are affected by the electoral cycle as parties adapt their objectives. Analysing longitudinal data on parties' attacks in the parliaments of Belgium, Croatia, and the UK (2010-2020), we find that when elections draw closer parties' use of attacks, trait attacks, and uncivil attacks increases. We also find support for the notion that not all parties' attack behaviour is equally impacted by the electoral cycle, as parties differ in sensitivity to the electoral cycle based on risk acceptance. Overall, the impact of the electoral cycle on parties' strategic choices in general, and attack behaviour specifically, should not be ignored.
