Incumbent Democrat Greg Stanton faces Republican Zuhdi Jasser and No Labels candidate Tisha Benoit in Arizona’s 4th Congressional District, a suburban Phoenix area rated solid Democratic by forecasters. Stanton’s primary victory and the district’s consistent Democratic performance in recent cycles underpin trader consensus around a 15–25 point Democratic margin, with the 20–25 point bucket leading at 31%. The race remains competitive on margins because the district’s partisan lean has narrowed in prior elections and national midterm dynamics could influence turnout among suburban voters. With three weeks until the November 3 general election, limited new polling and the absence of major campaign developments keep probabilities clustered in the mid-range buckets rather than pushing toward larger or narrower spreads.
