The race between Democratic incumbent Marie Gluesenkamp Perez and Republican challenger John Braun remains tightly contested ahead of the November general election, with recent polling averages showing a virtual dead heat and trader-implied probabilities reflecting balanced win odds. The district's Republican lean from prior presidential results contrasts with Perez's prior victories and stronger fundraising edge, while a recent Cook Political Report shift to Lean Democratic highlights national headwinds for Republicans. High undecided voter shares, negative impressions of both candidates, and focus on local economic concerns sustain the close positioning. Shifts in turnout patterns, particularly in Clark County, or further national developments could widen the margin in either direction.
