All the comforts of a Waldorf Astoria city-view suite did not, at that moment, seem to cheer Jasmine Crockett. The 44-year-old Texas Democrat known for her viral comebacks was frowning as she walked into her hotel room in Atlanta last month. She glanced around before pulling an aide into the bathroom, where I could hear them whispering. Minutes later, she reemerged, ready to unload.

She was losing her race to serve as the top Democrat on the House Oversight Committee, she told me, a job she felt well suited for … Crockett was starting to feel a little used. Some of her colleagues were “reaching out and asking for donations,” she said, but those same colleagues “won’t even send me a text back” about the Oversight job.

To Crockett, the race had become a small-scale version of the Democratic Party’s bigger predicament. Her colleagues still haven’t learned what, to her, is obvious: Democrats need sharper, fiercer communicators. “It’s like, there’s one clear person in the race that has the largest social-media following,” Crockett told me.
