  The HMP buy may represent a final attempt to break through in difficult districts rather than proof of a decisive Democratic advantage. Republicans could still hold enough incumbents through turnout, ticket-splitting, and Congressional Leadership Fund counterspending.

  Localized Ad Impact

  The $8.5 million buy changes the margins in the five Republican-held districts but does not materially alter the national balance of power. The spending matters for individual candidates and committee narratives more than for markets or federal policy expectations.
