Kentucky’s 4th congressional district features an open seat after incumbent Thomas Massie lost the Republican primary to Ed Gallrein, setting up a general-election matchup against Democrat Melissa Strange. The district’s strong Republican lean has supported expectations of a GOP victory, yet trader pricing centers on a 5-15% margin because late-cycle polling showed the candidates closely matched amid questions over Gallrein’s favorability and independent-voter preferences. Fundraising disparities and the presence of a Libertarian candidate have also factored into assessments of the final spread. Upcoming vote counting and any late shifts in turnout patterns could still influence resolution within the leading outcome range.
