"In a two-party system, it can well happen that the winning party has only a small majority. The members of the winning party can then threaten their party that if they don`t get something personally for themselves or their constituents then they would cross over to the opposition and bring down the government. Under threat, the government would be more concerned to retain the support of the members than to govern the country properly. Only when the government party has a big majority in a two-party system or a multi-party system can the government focus on governing and not on politics within the government party in order to remain in power."
