In the United States, prior to running as a party nominee in a presidential election, a potential candidate first has to win primary elections that are restricted to members of the potential candidate’s party. For instance, multiple candidates for the Democratic Party’s nomination must compete first among only Democrats to earn the party’s nomination before competing against the Republican Party’s nominee in the general election. Can you use our median voter model to argue that candidates for the Democratic Party’s nomination will initially position themselves to the left of the median voter but will then succeed in the general election (against the Republican nominee) only to the extent to which they can “move to the center” in the general election campaign?
