The Marquette Law School conducted a pre-debate poll from August 28 to September 5, surveying 738 Wisconsin residents regarded as likely voters. This poll took place right before a critical debate scheduled on Tuesday.

Kamala Harris is presently leading with a four-point margin in this vital swing state. However, voter preferences are strongly correlated with religious affiliations, revealing deep divides and potential strategies for the candidates.

Religion Plays a Crucial Role in Voter Preferences

Religious beliefs are significantly swaying voters' preferences in this election cycle. Christians predominantly support Trump, with 75% of born-again Christians and 54% of Catholics favoring him.

In contrast, Harris finds strong support among voters who identify as atheists, agnostics, or those from other non-Christian faiths. A clear majority of these voters, 82%, support Harris, reflecting her appeal among secular demographics.

Examining Favorability Ratings and Issue-Based Support

Harris boasts a slightly better favorability rating overall compared to Trump, standing at 47% against Trump’s 43%, with disapproval ratings at 51% and 56%, respectively.

Voters believe Harris performs better on abortion policy, while they favor Trump on immigration and border security. These issues highlight the key policy differences driving voter decisions.

Non-Protestant and non-Catholic voters show a stark contrast, with 55% supporting Harris and 30% backing Trump. Mainline Protestants are evenly split, illustrating how different religious groups impact voting choices.

Shifting Trends and Candidate Dynamics

Frequent church attendees lean toward Trump, strengthening his support among predominantly Christian groups. Voter discontent for both candidates has slightly dropped since July, from 11% to 8%.

In July, polls showed Harris and Trump nearly tied, but by September, Harris has a slight lead, signaling a shift in voter sentiment.

Robert F. Kennedy Jr. on the Wisconsin ballot has captured 6% of the vote, highlighting his potential impact on the election's dynamics.

Key Issues and Independent Voter Concerns

Economic worries remain a key concern, especially among independent voters who could sway the election. Republicans list economic issues among their top priorities alongside immigration and border security.

Democrats, meanwhile, focus more on abortion policies than economic issues, highlighting different voter priorities. This difference shapes where each candidate might target their campaign.

The survey’s margin of error is ±4.7%, advising caution in interpreting results, particularly in an unpredictable battleground state like Wisconsin. Voter preferences based on religious beliefs and issue priorities show the nuanced strategies needed to win over varied voter segments.
