2008 New Jersey Democratic presidential primary
The 2008 New Jersey Democratic presidential primary took place February 5, 2008, also known as Super Tuesday. With 107 pledged delegates at stake, New Jersey was a significant battleground in the Democratic nomination race between Senators Hillary Clinton and Barack Obama.
Hillary Clinton won the primary amid record-breaking turnout. Her margin of victory was narrower than early polling had projected but contradicted Barack Obama’s late surge in polling and strong performance in urban areas.
Campaign
Hillary Clinton was considered the frontrunner to win New Jersey's primary given her strong name recognition and institutional support in the state. She had significant endorsements from key state figures, including Governor Jon Corzine, Assembly Speaker Joseph Roberts and several county Democratic chairpersons. The vast majority of Democratic state legislators also endorsed Clinton.Barack Obama secured endorsements from prominent local leaders, such as Newark Mayor Cory Booker and Jersey City Mayor Jerramiah Healy. These endorsements were viewed as bolstering Obama's appeal among urban and younger voters.
