It’s hard to imagine a candidate with friendlier looks, a more harmless demeanor and a gentler-sounding surname than Conor Lamb.
It’s hard to imagine a message for the G.O.P. scarier than the one that Lamb, a Democrat, just delivered in a special House election in Pennsylvania’s 18th district, where he led his Republican opponent, Rick Saccone, by less than 1,000 votes in a race that remained too close to call on Wednesday morning .
Lamb declared victory. But even if he somehow ended up losing, Democrats have reason to rejoice and Republicans to tremble.
