Incumbent Democrat Gwen Moore faces Republican Tim Rogers and independent Arthur Burks in Wisconsin’s 4th congressional district, a Milwaukee-based seat with a D+26 partisan voting index. Moore’s primary victory and consistent double-digit general election margins in prior cycles, including 74.8 percent in 2024, underpin trader pricing that heavily favors a Democratic win in the mid-50 to mid-60 percent range. Nonpartisan ratings classify the contest as solid or safe Democratic, with limited Republican fundraising, minimal polling movement, and no major campaign events or national shifts altering the baseline since the August primaries. The spread across adjacent margin buckets reflects uncertainty over exact turnout and vote distribution in a low-competition race, while the near-zero probability assigned to a Republican victory aligns with the district’s structural and historical patterns. Late-cycle developments such as unexpected turnout surges or candidate withdrawals could still adjust final percentages within the resolution window ending November 3.
