FDU Poll finds First Lady’s Candidacy Harms Murphy’s Approval

 

 

First Lady’s Candidacy Harms Murphy’s Approval

Murphy approval stable, but Senate race turns off independents and Republicans

Fairleigh Dickinson University, Madison, NJ, February 6, 2024 – Governor Phil Murphy’s approval ratings remain relatively high, but there is trouble on the horizon. According to the latest results from the FDU Poll, First Lady Tammy Murphy’s campaign for the US Senate seat currently held by Bob Menendez is driving down Governor Murphy’s approval and driving up disapproval among independents and Republicans in the state.

In the poll of New Jersey residents, Murphy’s approval sits at 46 percent, in line with his numbers over the past year, which have fluctuated between 44 and 48 percent. Forty percent of residents say that they disapprove of the job he’s doing as Governor, a figure that’s also largely unchanged over the past year.

“The governor can’t run for re-election, but these numbers still matter,” said Dan Cassino, a professor of Government and Politics at FDU, and the director of the poll. “High approval ratings give the governor leverage to get things done in Trenton; low approval means legislators may start to ignore him.”

The survey, which included a series of questions about this year’s Senate race in New Jersey, also included an experiment designed to measure the effect of First Lady Murphy’s candidacy on Governor Murphy’s approval. Half of respondents were randomly assigned to be asked about Murphy’s approval at the start of the survey (as is standard), while half were asked only after answering questions about the Senate race. The difference between the two groups reveals the effect of thinking about the Senate race on Murphy’s approval.

Overall, asking about the Senate race before asking about Murphy’s approval doesn’t impact his approval rating, but does increase his disapproval significantly, from 37 percent to 43 percent. The effect of the Senate race only becomes obvious when the data are broken down by party. While asking about the Senate race first marginally increases Murphy’s approval among Democrats (from 76 percent to 81 percent), it reduces it by 10 points among independents (from 42 percent to 32 percent), and 8 points among Republicans. It also increases disapproval by 12 points among Republicans and 21 points among independents (from 40 to 61 percent).

“Part of this is just linking the governor to national politics, rather than local issues, which is going to hurt him among independents and Republicans,” said Cassino. “But there also seems to be some resentment about the First Lady’s candidacy, and that could quickly drag the Governor down.”

In a sample of likely Democratic primary voters taken from the same poll, First Lady Tammy Murphy trails Democratic Congressman Andy Kim by 12 points, with Kim leading 32 to 20, and 31 percent still undecided. Sitting Senator Menendez has the support of 9 percent, and 8 percent of Democratic primary voters say that they’ll back labor activist Patricia Campos-Medina.

FDU Poll Ranks Among Top Tier Nationwide

The FDU Poll is in the top tier of polls nationwide. Poll aggregator Five Thirty-Eight has released its new rankings of polls ranking FDU 31st in the country, out of more than 500.

The rankings look at the error associated with a poll’s predictions and the degree to which the poll makes its methodology transparent. The FDU Poll scored high on both measures, with a pollscore accuracy ranking of -0.6 (lower figures represent less error and bias), and a transparency score of 8/10.

These scores are impressive when compared with other institutions. The overall ranking is better than that of many well-known polling groups like Gallup (35), Pew (38), SurveyMonkey (75) and Rasmussen (89).

Methodology

The survey was conducted between January 21 and January 28, 2024 out by Braun Research of Princeton, New Jersey. Most of the sample (777 respondents) were from a random digital dial sample of New Jersey residents; the remainder (238) were an oversample, taken from a list of adult New Jersey residents who have voted in previous New Jersey Democratic primary elections. Voter lists were obtained from Aristotle International of Washington, DC.  Weights were used to adjust the effective sample size to the appropriate level (872 respondents) and ensure that the oversample does not impact the overall representativeness of the sample.

201 of the surveys were carried out via live caller telephone interviews on landlines, 461 on live caller interviews to cell phones, and the remainder (353) were done on a web platform via weblinks sent via SMS to cell phones. Surveys were conducted only in English.

The data were weighted to be representative of the population of New Jersey residents, according to 2020 US Census data. The weights used, like all weights, balance the demographic characteristics of the sample to match known population parameters. The weighted results used here are balanced to match parameters for sex, age, education and race/ethnicity.

SPSSINC RAKE, an SPSS extension module that simultaneously balances the distributions of all variables using the GENLOG procedure, was used to produce final weights. Weights were trimmed to prevent individual interviews from having too much influence on the final results. The use of these weights in statistical analysis helps to ensure that the demographic characteristics of the sample approximate the demographic characteristics of the target population. The size of these weights is used to construct the measure of design effects, which indicate the extent to which the reported results are being driven by the weights applied to the data, rather than found in the data itself. Simply put, these design effects tell us how many additional respondents would have been needed to get the weighted number of respondents across weighted categories: larger design effects indicate greater levels of under-representation in the data. In this case, calculated design effects are approximately 1.4.

All surveys are subject to sampling error, which is the expected probable difference between interviewing everyone in a population versus a scientific sampling drawn from that population. Sampling error should be adjusted to recognize the effect of weighting the data to better match the population. In this poll, the simple sampling error for 872 New Jersey residents is +/-3.3 percentage points, at a 95 percent confidence interval. Including the design effects, the margin of error would be +/-4.6 percentage points, though the figure not including them is much more commonly reported.

This error calculation does not take into account other sources of variation inherent in public opinion studies, such as non-response, question wording, differences in translated forms, or context effects. While such errors are known to exist, they are often unquantifiable within a particular survey, and all efforts, such as randomization and extensive pre-testing of items, have been used to minimize them.

The FDU Poll is a member of the AAPOR Transparency Initiative and is devoted to ensuring that our results are presented in such a way that anyone can quickly and easily get all of the information that they may need to evaluate the validity of our surveys. We believe that transparency is the key to building trust in the work of high-quality public opinion research, and necessary to push our industry forward.
