In September 2010，Venezuela held the National Assembly election to elect the 165 deputies. The United Socialist Party of Venezuela （its Spanish acronym is PSUV），the ruling party，failed to gain a two-thirds supermajority. The main opposition parties created the Coalition for Democratic Unity （its Spanish acronym is MUD） and succeeded in winning over one third of the total seats. They will gather strength in the National Assembly to challenge the Chavez government. The election results show the deeply-rooted political polarization in Venezuela. President Hugo Chavez and PSUV are pressed to take actions to rebuild popularity to meet the upcoming 2012 presidential election.
