This paper relies on the variation of terror attacks across time and space as an instrument to identify the causal effects of terrorism on the preferences of the Israeli electorate. We find that the occurrence of a terror attack in a given locality within three months of the elections causes an increase of 1.35 percentage points on that locality’s support for the right bloc of political parties out of the two blocs vote. This effect is of a significant political magnitude because of the high level of terrorism in Israel and the fact that its electorate is closely split between the right and left blocs. Moreover, a terror fatality has important electoral effects beyond the locality where the attack is perpetrated, and its electoral impact is stronger the closer to the elections it occurs. Interestingly, in left-leaning localities, local terror fatalities cause an increase in the support for the right bloc whereas terror fatalities outside the locality increase the support for the left bloc of parties. Given that a relatively small number of localities suffer terror attacks we demonstrate that terrorism does cause the ideological polarization of the electorate. Overall, our analysis provides strong empirical support for the hypothesis that the electorate shows a highly sensitive reaction to terrorism.

This article investigates the interaction between terror attacks and electoral outcomes in Israel. The authors analyze a dynamic model of reputation that captures the salient characteristics of this conflict. The equilibrium of the theoretical model generates two precise empirical predictions about the interaction between terrorism and electoral outcomes. First, the relative support for the right-wing party is expected to increase after periods with high levels of terrorism and to decrease after periods of relative calm. Second, the expected level of terrorism is higher when the left-wing party is in office than it is during the term of the right-wing party. The authors test these hypotheses by using a newly created data set on terrorist attacks in Israel between 1990 and 2003. The first hypothesis is strongly supported by data culled from public opinion polls about the Israeli electorate’s political preferences. The second theoretical hypothesis is strongly supported by the three Israeli governments to which the theory can be applied that served during the studied time period.
