The special election for Pennsylvania House District 12, triggered by the March 2026 resignation of the prior Republican incumbent, features Republican Scott Timko and Democrat Brandon Dukes as the primary general-election contenders on the August 18 ballot. Timko secured the GOP nomination in a close May primary, while Dukes advanced unopposed on the Democratic side. The district spans portions of Butler County and surrounding areas, where recent primary margins and limited polling data reflect a competitive partisan balance. With the vote roughly one month away, trader consensus at even odds across listed outcomes underscores uncertainty over turnout patterns, local issue salience, and any late campaign developments that could shift support between the two nominees or elevate write-in or alternative candidates.
