The open seat in Louisiana's 5th Congressional District, vacated by Rep. Julia Letlow's Senate bid, features a crowded Republican primary field where state Sen. Blake Miguez holds a modest polling lead and substantial fundraising advantage after securing President Trump's endorsement as a "MAGA Warrior." Recent U.S. Supreme Court action striking down the state's congressional map as an unconstitutional gerrymander has suspended the May 16 primary and prompted a special legislative session on redistricting, introducing procedural uncertainty that keeps probabilities compressed among the top contenders. Residency challenges against Miguez and high undecided voter shares further fragment support, while limited polling and campaign spending by figures like state Rep. Michael Echols and Misti Cordell maintain close positioning. Resolution of the map dispute, additional endorsements, or late debate performances could shift momentum before voters decide.
