Turkish presidentialism increases the prominence of the executive at the expense of the legislative branch and concentrates power in the office of the president. Executive aggrandizement will deepen ideological polarization and electoral mobilization by significantly raising the stakes of the game for both the incumbent and the opposition. As such, we posit that the new presidential system will institutionalize the de facto personalism and majoritarian rule that the AKP has hitherto established in recent years. This trend is likely to trigger a transition from a competitive authoritarian to hegemonic electoral authoritarianism in case of Tayyip Erdoǧan's election, thus placing Turkey on par with the strongest executive systems around the globe such as Russia and Venezuela.EnglishAKPAnd TurkeyErdoǧanMajoritarianismPresidentialismArticle10.1017/rms.2018.10
