Conor Lamb’s triumph in Trump country is being heralded by conservative Democrats as a major victory in their ongoing turf battle with the far left — and an object lesson on the kind of candidates the party needs to promote and win to take the House in November.

The 33-year-old Marine veteran personally opposed abortion (while backing abortion rights), described a $15 minimum wage as “high” and ran an ad showing him doing target practice with a machine gun — none of which sit well with the ascendant Democratic base.

“He didn’t run on an identity politics, one-size fits all message,” said Rep. Kurt Schrader (D-Ore.), co-chairman of the Blue Dog PAC, the fundraising arm for the conservative Democratic coalition. “He ran on the Blue Dog message.”

For the Blue Dogs, Lamb’s successful center-left campaign is proof that the Democratic Party’s “big tent” mentality is still a winning electoral strategy, despite an aggressive push from liberals for candidates that more closely adhere to the progressive purity made popular by the likes of Sens. Bernie Sanders (I-Vt.) and Elizabeth Warren (D-Mass.).
