Is Conor Lamb the new model Democrat? Or will progressives come for him next?

BRIDGEVILLE, Pa. – Since Democrats started bleeding moderates in 2009, the best course correction they’ve made was to step aside and let Western Pennsylvania Democrats pick Conor Lamb as their nominee for the 18th Congressional District.

Lamb is not a full-throated progressive. And a deep-blue progressive would not be within striking distance of winning this race in a suburban-rural congressional district, where, despite having a 25,000-voter registration advantage, Democrats didn’t even field a candidate in 2016.
