Looking at the Democratic race today, it’s easy to get lost in news cycles and distracted by rehearsed “moments,” the supposed currency of the primary debates. Because politics feels so staccato-burst crazy, with our phones sucking us into the present and draining our capacity for long-term thinking, it’s understandable that observers might think that winning the day is enough to win a campaign. It’s not. Successful candidates have a clear, consistent, and compelling point of view, delivered over and over again regardless of the audience, that allows them to build a coalition of voters, raise money, stay on the offense, and avoid the hourly traps presented to them by the media and online outrage merchants.

Remarkably, with two-dozen Democrats running for president, there is only one candidate running this kind of campaign. Her name is Elizabeth Warren. And with the second round of primary debates upon us, no one is better positioned to bridge the divisions on the left and become the Democratic nominee.

Sure, Joe Biden and Bernie Sanders are still leading the race, thanks to their near-universal fame, but their support has creaked and wobbled with each passing day. Kamala Harris, too, has planted herself near the top of the field, but since announcing her campaign in January, Harris’s support ticked up, then down again. After her debate clash with Biden—a moment!—she saw another bump but then began to fade again, suggesting that primary voters like her but still have questions. Warren is the only serious Democrat running for president who has steadily grown her support over the duration of the campaign, a better indicator of success than any sugar-high bump in the polls.

In Iowa and New Hampshire, Warren has passed Sanders, her rival on the progressive left. But Warren, a capitalist, isn’t just siphoning voters from the Revolution. She’s appealing to a variety of Democrats. A Morning Consult poll this month exploring the backup choices of primary voters found that among Warren supporters, 33% picked Harris as their second choice, with 20% picking Sanders and 15% picking Biden. That suggests Warren and Harris are competing for similar voters—women and college-educated liberals—but also that Warren has the attention of moderates and working-class whites. Crowded primaries are won by building coalitions that cut across states, and Warren is doing precisely that. “She is going to pick up a lot of support from Bernie, sure, but at some point everyone is going to have to address her,” said South Carolina state Rep. Kambrell Garvin, an African American who has endorsed Warren in the primary state. “Harris has to contend with Warren in the race. So does Joe Biden. So does everyone. Can you say that about another candidate? I just do not see any other candidate with the potential to corral a movement like she does.”

How is Warren doing this? She has both a message and a rationale for running. They are not the same thing, but they are entwined. A select few candidates have a Big Idea: Biden is running on restoring American values, Sanders on radical change, Pete Buttigieg on generational justice. But they have not quite explained, as well as Warren has, why they are the best person to step into the White House right now. “In a crowded field, having a strong message is important, but so is a rationale for running—and Senator Warren has both,” said Eric Koch, a New York-based Democratic strategist. “In 30 seconds, she can tell you not only why she’s in the race but what she’s going to do once she wins. She’s done a great job running a focused campaign that keeps an emphasis on her message, experience, and vision—while avoiding the kind of pointless Twitter drama that doesn’t actually win you votes.” Warren’s themes of economic justice and informed experience—“Warren Has a Plan for That!”—make sense to a cross-section of Democrats frustrated by inequality and the slapdash incompetence of the Trump administration. Unlike Biden and Sanders, she is a new face on the presidential campaign stage. She calls herself a fighter, and has backed up that pledge with policy agenda so liberal and far-reaching that it would have made Rahm Emanuel throw up in his mouth not five years ago.
