In an upset that Democrats are going to look back on for a long time, 28-year-old Alexandria Ocasio-Cortez, a leftist outsider, has defeated 10-term incumbent Rep. Joe Crowley, chairman of the House Democratic Caucus, in New York’s 14th congressional district. She will almost certainly be the youngest woman to ever elected to Congress, and Crowley will not be the next Speaker of the House.

“Shocking,” one senior Democratic House aide said of the result Tuesday night, noting that Crowley had been spending “a ton of time” in the district.

“They were projecting confidence.”

This is already being seen as the Democratic version of then-House Majority Leader Eric Cantor’s primary defeat to Dave Brat in 2014. (Before Republicans crow too much about how the radical Democratic base is taking over the party, helping Republicans’ chances, they should recall how the 2014 general elections went.) But it’s arguably bigger. This is new territory for Democrats.

By the time Cantor lost, establishment Republicans were already accustomed to ideologically driven upsets from the base. When the party was overflowing with enthusiasm in the 2010 electoral cycle, party favorites lost Senate primaries in Nevada, Kentucky, Colorado, Delaware, and Utah. They lost important ones, again, in Indiana and Missouri in 2012. Dozens of House primaries went the wrong way. Cantor’s was the most stunning and highest-ranking upset in a Republican primary—well, until the presidential primary two years later—but fear of the base had already been a daily fact of life for national Republicans for years.

Primary upsets against deep-rooted literal party bosses don’t usually happen on the Democratic side. The Democratic Congressional Campaign Committee, for the most part, has gotten the candidates it wanted; the Democratic Senatorial Campaign Committee is not having much trouble ushering its preferred candidates through primaries, either. The little upsets that bubble up into this kind of climax upset were nowhere to be seen. Each district is different, but elected Democrats tend to think they have better control over their base.

Crowley’s loss will do more than instill the fear of God into Democratic members for years to come. It also leaves Democrats without a likely successor to Rep. Nancy Pelosi. Crowley was waiting patiently, in the event that Democrats won the majority but Pelosi could not cobble together 218 floor votes for the speakership. He was the last one standing from a generation of members who waited, fruitlessly, to ascend in the House after the Pelosi-Hoyer era—think of Rahm Emanuel, Chris Van Hollen, and Xavier Becerra—and now Crowley is gone, too, and not even for a new job.

In the short term, Pelosi may have crossed another potential challenger off of her list, but the bigger picture can’t be good for the existing Democratic leadership structure. Crowley, for all his accumulated power, just got taken out on the mantra of generational change. This presents an argument, for Pelosi’s detractors in the conference, that the rest of the leadership should follow suit.
