The sudden coronation of Kamala Harris as the de facto presidential nominee has reminded Democrats of something important they might have forgotten over the past decade: Enthusiasm is a one helluva drug. With apologies to Hillary Clinton and Joe Biden, Democrats haven’t been this fired up for a presidential nominee since Barack Obama exploded onto the national scene in 2008. That was 16 years ago! Sixteen years since a Democrat has inspired authentic passion, spawning merch, memes, volunteer sign-ups, voter registration, and a tsunami of small-donor cash. The $200 million that Harris has raised since taking charge of the Biden campaign operation—a number that could reach $300 million by the end of the month—is impressive enough. But the standout statistic is how much of that money came from first-time donors: 66 percent.
