WASHINGTON_Alexandria Ocasio-Cortez is young, Latina, and boldly progressive _ in other words, everything the Democratic Party's leadership is not.
The party's activists are ready for that to change.
The 28-year-old socialist's historic victory Tuesday over incumbent Democratic Rep. Joe Crowley is, activists say, a warning to the party's old, white and cautious leadership that Ocasio-Cortez won because she represents the party's new base of voters.
