This article approaches the puzzle of how parties can strategically anticipate coalition formation and make themselves more attractive coalition partners in their electoral strategies. It argues that parties can strategically adjust the salience of issues that are secondary to them in pursuit of increased ‘coalitionability’. It tests the argument through analysis of the salience of secondary policy dimensions of up to 232 European parties between 1970 and 2019, finding evidence that parties adjust the levels of salience of their secondary dimension in response to the probability of their being included in a coalition government and their distance from the coalition in which they are most likely to be included.
