Incumbent Republican Speaker Mike Johnson faces limited opposition in Louisiana’s 4th congressional district jungle primary scheduled for November 3, 2026. Recent qualifying filings show only minor challengers, including Democrat Conrad Cable and a handful of others with negligible fundraising or name recognition. The district’s strong Republican tilt and Johnson’s established incumbency advantage position him to consolidate the large majority of votes in the first round. With no significant intra-party splits or well-funded Democratic contenders reported, the primary structure favors an outright majority rather than a runoff. Trader consensus at 92% reflects this low-risk profile and the absence of late developments that could fragment support.
