Italian party coalitions (from both the centre-left and the centre-right) have enacted an average of 57% of the pledges included in their common manifestos. In relative terms, Italian political parties keep their electoral promises much less than parties governing in single-party government, but slightly outperform those that form post-electoral coalitions. Although this finding contradicts the widespread pessimism about Italy's performance, it also illustrates that there is no significant advantage to bipolarism and the existence of a common programme as opposed to situations where coalitions are formed after the elections. This might explain Italians’ dissatisfaction with the way democracy works in their country.
