Conor Lamb weathered $10 million in attack ads cartoonishly calling the Democratic candidate in Pennsylvania’s special election a member of Nancy Pelosi’s liberal “flock.”

Now other Democratic hopefuls are looking to adopt Lamb’s strategy — he repeatedly and bluntly disavowed the Democratic leader — in their own competitive races. It raises the prospect of a slate of Democratic hopefuls running against the party’s House leader as they try to neutralize one of the GOP’s go-to attacks — a pillar of Republicans’ plan to keep the House majority in November.

A half-dozen Democratic House members and candidates told POLITICO in interviews that they had been closely monitoring how Lamb handled the Pelosi attack. In one notable ad, the 33-year-old Marine faced the camera and called the claim that he’s a clone of the Democratic leader “a big lie. I’ve already said on the front page of the newspaper that I don’t support Nancy Pelosi.”
