• Target Exceedance: When a candidate's performance in a specific area surpasses the expected or "target" percentage for their party.
• Range Model: A statistical tool that estimates a candidate's potential vote share within a defined range, used to determine if there's a clear winner.
• Exit Polls: Surveys conducted with voters as they leave polling stations to gather information on demographics, motivations, and key issues influencing their vote.
• Voter Demographics: The characteristics of the voting population, such as race, ethnicity, and economic status, and how they vote.
• Issue Salience: The importance voters place on specific issues, such as the economy, affordability, and energy prices, when making their voting decisions.

New Jersey Gubernatorial Election Projection: Mikie Sherrill Declared Winner

This report details the CBS News projection of Mikie Sherrill, the Democratic nominee, as the winner of the New Jersey gubernatorial race, defeating Republican nominee Jack Ciattarelli. This marks Ciattarelli's third consecutive loss in his bid for the governorship.

Methodology for Election Projection

1. Pattern Analysis in County-Level Results: CBS News Elections and Surveys Director Anthony Salvanto explained the projection methodology, emphasizing the importance of identifying patterns in incoming vote counts.

• Target Exceedance: Sherrill was consistently meeting or exceeding the expected vote percentages for a Democrat in various counties.
• Specific County Examples:
  • Bergen County: Sherrill surpassed Kamala Harris's percentage in this county.
  • Passaic County: A closely watched county where Sherrill was exceeding Kamala Harris's percentage, despite Donald Trump having previously flipped this county for Republicans.
  • Morris County: Another county flipped by Donald Trump in the 2024 election, where Sherrill was performing better than expected.
• Aggregation of Patterns: By observing these patterns across multiple counties, a clear trend emerged indicating Sherrill's victory.
• Early Vote Strength: A strong showing in the early vote for Sherrill was also a significant factor contributing to the projection.

2. Range Model Analysis: The projection was further solidified by the separation of candidate ranges in the range model.

• Initial Overlap: Previously, the estimated vote ranges for Sherrill (blue) and Ciattarelli (red) showed an overlap, indicating uncertainty.
• Separation of Ranges: As more data came in, the ranges separated, meaning Sherrill's lowest estimated vote share was higher than Ciattarelli's highest estimated vote share. This definitive separation allowed for the projection of Sherrill as the winner.
• Transparency: Salvanto highlighted that this process of showing the data and modeling is how CBS News "shows its work" in making election calls.

Exit Poll Findings and Voter Motivations

CBS News Congressional Correspondent Caitilin Huey-Burns provided insights from exit polls, explaining the underlying reasons for the projected outcome.

• Key Issues:

  • Economy and Affordability: This was a dominant issue across all covered races, particularly in New Jersey.
  • Financial Struggles: Among voters who reported falling behind financially, Sherrill held a lead.
  • Energy Prices and State Taxes: High energy prices and state taxes were specifically mentioned as concerns by candidates and voters.

• Demographic Performance:

  • Non-White Voters: Sherrill secured 74% of non-white voters, a crucial demographic for her lead in New Jersey.
  • Latino Vote: Sherrill led Ciattarelli 2 to 1 among Latino voters. This is a significant gain compared to the previous election, where Biden won only 51% of the Latino vote. This is particularly noteworthy given the substantial Latino population in New Jersey and Donald Trump's gains with this demographic in the last election.
  • Independent and Suburban Voters: Sherrill also showed leads among these voter groups.

• Referendum on Donald Trump:

  • Influence of Trump: Half of New Jersey voters indicated that Donald Trump played a role in their vote.
  • Opposition to Trump: The majority of those who cited Trump's influence did so to oppose him.
  • Limited Impact: 46% of voters stated that Trump was not a significant factor in their decision.
  • State Political Landscape: New Jersey is characterized as a "blue state," having voted for Kamala Harris in the last presidential election and currently having a Democratic governor, suggesting a continuation of this trend.

Campaign Headquarters Atmosphere

Theresa Duncan reported from Jack Ciattarelli's campaign headquarters, describing the mood as skeptical and subdued.

• Voter Sentiment: Attendees were hesitant to concede the race, with some observing the incoming results on their phones and expressing disappointment.
• Lack of Candidate Appearance: There was no public appearance or statement from the Republican candidate, Jack Ciattarelli, or his campaign.
• Mikie Sherrill's Statement: Mikie Sherrill posted on X, expressing her honor to be elected the 57th Governor of New Jersey and promising to listen, lead with courage, and serve the people. Her campaign motto, "Let's land this thing," appeared to be realized with this victory.

Historical Context

The report briefly mentioned that four years prior, Jack Ciattarelli came within three percentage points of incumbent Democratic Governor Phil Murphy, suggesting this may have been his closest opportunity for victory.

Conclusion

The CBS News projection of Mikie Sherrill as the winner of the New Jersey gubernatorial race is based on robust data analysis, including pattern recognition in county-level results and the separation of candidate vote ranges. Exit poll data reveals that key issues such as the economy and affordability, coupled with strong support from non-white and Latino voters, were instrumental in Sherrill's victory. The election also appears to have served as a partial referendum on Donald Trump, with a significant portion of voters casting their ballots in opposition to him. The outcome reflects New Jersey's established Democratic leanings.
