Rep.-elect Conor Lamb made national waves with an improbable win last week in Pennsylvania’s 18th Congressional District. He faced down $10 million in outside money funneled to his opponent by corporate and right-wing interests. He fought through a barrage of incessant, hyperpartisan attacks blanketing the airwaves. He was abandoned by his own party’s national infrastructure in a district that hadn’t elected a Democrat in nearly 15 years. And he still came out on top.
