Running mate

Role and responsibilities

Functions of a running mate vary by system. In many presidential systems the partner campaigns nationally, represents the ticket at events, and prepares to assume the presidency if the top candidate cannot serve. In other cases the role is largely symbolic or limited to specific duties assigned by the principal candidate. Legal provisions also differ: some constitutions make the vice-presidential office part of the executive succession chain, while others assign separate mandates.

How running mates are chosen

Parties and candidates weigh several factors when naming a running mate. Common considerations include:

• Geographic or regional balance to broaden electoral appeal.
• Ideological or factional balance within a party or coalition.
• Experience or perceived readiness to govern.
• Demographic representation—gender, ethnicity, religion, or age—to attract specific voter groups.

Selection can be strategic: a ticket may seek to unify rival party wings, secure a swing region, or reassure voters about competence and continuity.

History and variations

The use of joint tickets and paired candidates is now widespread in national elections, though arrangements differ. In some countries president and vice president are elected together on a single ballot; in others they may be chosen separately, which can lead to cross-party officeholders. Parliamentary systems typically do not use the running-mate model for head-of-government selection, relying instead on party leadership and legislative majorities.

Running mates sometimes come from coalition partners or rival factions to cement alliances. Notable modern examples include international tickets such as Joko Widodo and Jusuf Kalla, who were publicly described as running mates during Indonesia's presidential contests. The choice of partner can influence voter perceptions, raise issues of succession and vetting, and shape the governing agenda if the ticket wins.
