- The Democratic Congressional Campaign Committee added von Wilpert to its Red to Blue program to provide fundraising and organizational support, a move reported after the primary.
- The National Republican Congressional Committee placed Desmond in its MAGA Majority program, signaling national investment and highlighting his endorsement from President Donald Trump.
- Von Wilpert has retooled her message to "Take Back Congress" and plans an intensive door-to-door ground game after saying her team knocked on 26,000 doors during the primary.
- The district was reshaped by Proposition 50 to include Palm Springs and parts of San Diego and Riverside counties, which made CA-48 more competitive and raised its strategic importance for both parties and outside spending.
