Elizabeth Warren for president?

It was one of those important-but-dull hearings that don’t even get broadcast on C-SPAN 3.

An obscure subcommittee was taking expert testimony on patient safety Thursday, and only four of its 14 members bothered to show up. Several of the public seats were empty, too.

But Elizabeth Warren was in her element.

The committee’s most junior member was the first senator to arrive, five minutes early, and when it was her turn to question the witnesses she blew past the time limit. It was as if she were back at Harvard Law School, using the Socratic method to lead students to her desired conclusions in favor of stricter standards for hospitals and prescriptions.

“Dr. Jha? … OK, good, and Dr. Gandhi wants to add to that? … Dr. Pronovost, you want to get into this? … OK, so we’ve got payment responsibility. Very powerful. Dr. Disch? … What would be the next step?”

She nodded, waved, smiled and coaxed her pupils along with “right” and “mm-hmm.” When the chairman finally cut her off, Warren had a concern. “I do want to be sure Dr. James gets a chance to participate,” she said.

Indeed, his class-participation grade was riding on it.

Watching Warren combine her encyclopedic knowledge of the regulatory system with her three decades of experience as a professor, it was difficult to picture her launching a long-shot bid for the presidency.

A draft-Warren boomlet is underway, with the purpose of encouraging her to challenge Hillary Clinton for the Democratic nomination in 2016. It is eerily similar to the movement that propelled Barack Obama to challenge Clinton eight years ago even though, like Warren, Obama had served just two years in the Senate. But while Warren is a compelling figure — a feisty populist at a time of inequality and resentment — her actions since arriving in the Senate suggest she has neither interest in nor aptitude for a presidential candidacy.

I wanted to write about the Warren presidential hoopla, so I mentioned to her spokeswoman, Lacey Rose, that I’d buttonhole the senator after the subcommittee meeting. “We don’t do hallway interviews,” Rose replied. She said she would “see about” a phone interview, but six hours later reported that she “couldn’t make this work.” (Warren had been on the Senate floor, writing thank-you notes on official stationery while taking a turn in the presiding officer’s chair.)

This, I learned, is typical. Congressional reporters say that Warren is unusual among senators in her refusal to take questions. She is invariably guarded by staff as she walks about the Capitol, and the few interviews she has done have generally been on defined topics (such as her book) where the risk of unanticipated questions is low.

Such reticence is certainly not a fault. But it is the behavior of a lawmaker who plans to keep her head down and to do her job as a legislator — not somebody who is contemplating the glare of the national spotlight. She has plunged into policy and is doing whatever she can to shield herself from unscripted moments.

At this point in 2006, Obama had already hired national political consultants David Axelrod and Anita Dunn. He clearly had greater ambitions: The Washington Post reported then that Obama himself “suggested that a presidential bid is a matter of when, not if.”

Warren’s apparent reluctance is well grounded because Democrats may be less willing in 2016 to put their hopes in another neophyte. Liberals saw Obama as purer than Clinton, but his inconsistent leadership has disappointed many of them. Warren is, if anything, less known than Obama was; he served on the Senate Foreign Relations Committee, but all of Warren’s committee assignments are domestic.

None of this has stopped the “Ready for Warren” movement, which last week launched a website with a draft-Warren petition. “Run, Elizabeth, Run!” was the headline atop John Dickerson’s Slate piece Thursday.

In The Wall Street Journal, conservative John Feehery proclaimed that Warren “would beat the former first lady for the presidential nomination.” In recent months Warren has made a dozen or so appearances in eight states for Democratic candidates.

It is, in other words, a bit like Obama in ‘06. Then, the young senator was getting more than 300 requests a week for appearances and drawing overflow crowds. But there is a crucial difference. As The Post reported at the time, Obama’s Senate colleagues were grumbling about him being “drawn to news conferences and speeches more than to the hard details of lawmaking.”

Warren, by contrast, is all about the hard details.
