In the intense 2014 Brazilian presidential election，Dilma Rousseff’s re-election ensured the Labour Party in power continuously，but also demonstrated the challenges that the Labour Party is facing in its party construction and its governance model of Brazil in recent years，such as the new，complicated pattern of political parties，new political ecology，and new social structure. There is an urgent need for the Labour Party’s Government to make a timely policy transformation. The Rousseff’s campaign reflected the idea “Seeking Changes during Continuing”，but judging from the current conditions，the space of policy change is limited，“Continuing” will remain the key to the Rousseff’s second mandate. In the next 4 years，Rousseff will face greater pressure on ensuring regime stability，recovering economic growth，social policies transformation，and regaining international influence，etc. Whether the Labour Party would reverse the current predicament or not depends largely on how it deals with the above challenges.
