Abstract: How do rulers and opposition use competing political rallies to gain support from pivotal actors? I model rallies as Blackwell experiments that generate information about the regime. The ruler and the opposition interact repeatedly, deciding whether to call a rally and what information structure to employ. At each stage, a pivotal elite may end the contest by choosing a side. The theory predicts that the sequence of rallies depends on relative strength: the weaker side initiates a rally due to the risk that the game may end. The stronger side responds with a counter-rally only if the previous rally draws a high turnout. When the two sides differ greatly in strength, rallies tend to be more informative; when they are relatively equal in strength, the sequence of rallies and regime survival become less predictable. These results provide a theoretical foundation for studying competing rallies using case studies and empirical analysis.
