A newly formed super PAC, linked to Republicans, has poured more than $1 million into three Democratic congressional primaries, aiming to install weaker challengers and keep the House in GOP hands. The group backed a Texas sex‑therapist accused of antisemitism, as well as candidates in Pennsylvania and Nebraska, turning intraparty battles into battlegrounds for national control.

Republican influence also shows up in a separate PAC aligned with House leadership, which is buying mailers in California’s Central Valley race, promoting a progressive candidate against a moderate rival. In all four contests, the spending targets Democrats tied to the party’s “red to blue” program, a strategy that could swing the narrow 217‑to‑212 majority.

The covert spenders, such as Lead Left PAC, keep donor identities hidden, routing money through LLCs and using metadata linked to Republican donation processors. Their ads mirror those run by the American Action Network, underscoring a coordinated effort to shape primary outcomes. Democratic leaders label the practice a “callous political ploy,” warning that unchecked dark money could destabilize elections.

With the House advantage razor‑thin, every dollar spent in a primary can tip the balance. Republicans’ strategy of backing fringe candidates signals a shift toward aggressive intraparty warfare, while Democrats scramble to counteract. The episode underscores how political finance now operates as a direct battleground, reshaping campaign dynamics and threatening the integrity of electoral competition.
