Choosing whether to end a hard-fought White House bid is only half of it.

Elizabeth Warren, the Massachusetts progressive who went from leading economics expert to senator and presidential candidate within a decade, also faces the challenging decision of who to endorse in exiting the 2020 race after a brutal Super Tuesday in which she didn’t win a single state — not even her own.

She announced the end of her campaign Thursday morning.

While the Warren campaign has long maintained that it would battle over the course of “the long haul” to face President Donald Trump in November, senior staff on Wednesday acknowledged that expectations were not met. Campaign manager Roger Lau said in a statement that the campaign “fell well short of viability goals and projections, and we are disappointed in the results.”

Former Vice President Joe Biden, who rallied with support from African Americans, moderates, older voters and late deciders as Pete Buttigieg and Sen. Amy Klobuchar left the race, took not only Massachusetts but more than half the Super Tuesday states.

Sen. Bernie Sanders, the progressive Vermont independent who challenged the Democratic establishment with a presidential run first in 2016 and again in 2020, won a handful of states including the biggest delegate stronghold, California. But his recent rise hasn’t been enough to block a surging Biden, who dominated in South Carolina after an impactful endorsement from U.S. Rep. James Clyburn.

After her performance on Super Tuesday, Warren was assessing “the path forward” while the campaign kept plans under wraps.

She announced the end of her campaign Thursday, first speaking to her campaign staff before addressing reporters. Asked if she will endorse Biden or Sanders, Warren said, “Not today."

Speaking alongside her husband, Bruce Mann, and dog, Bailey, outside their Cambridge home, Warren said, “I need some space around this and I want to take a little time to think some more.”

Whom might she support?

And where would her voters turn — a moderate and well-known establishment Democrat who Warren has painted as too eager to compromise with Republicans? Or a Democratic socialist whose proposals are largely in synch with hers but who remains, she argues, a lawmaker who hasn’t gotten much done in decades?

“She’s got three bad choices,” political consultant Tony Cignoli said in an interview Wednesday. “She goes with Bernie, and immediately the establishment, colleagues in the Senate and House, are looking at her and saying, ‘you’re kidding?’ It ostracizes her a lot. Or she goes with Joe, and you’ll hear a cry from the liberal, progressive left, especially in Massachusetts. The Bernie people will be unforgiving.”

The third choice, Cignoli added, might be the worst: “Do nothing, piss off both sides. Holy smokes, you wanted to get into this arena, but this is a really tough spot for her.”

Scott Ferson, a Democratic strategist based in Boston, argued “doing nothing might be best" for Warren over the long term.

“I don’t know how you falter saying, ‘Thanks for your support ... now you can have at it,'" Ferson said with a chuckle.

Ferson said Warren never solidified her identity as a progressive who could move the needle if elected.

“At first, she seemed to say, ‘All you Bernie people will come to me because you’ll realize he’s done this before and I’m more electable.’ That didn’t quite work, because people weren’t abandoning Sanders," Ferson said. "And she never presented herself as a moderate alternative.”

He added that he didn’t think Warren supporters would automatically back the other progressive in the race. “If that was the case, they would have already been with Bernie,” he said.

Ferson, whose company Liberty Square Group performed polling in some primary states, added that Warren suffered from circumstances in which many voters in Massachusetts and other states remained undecided until just days ago.

“They could be a little agnostic about a candidate, but they were absolutely united in their hatred of Donald Trump,” he said, of Democratic voters. “And they’re trying to figure out who’s the best candidate to go against him."

Biden was “on the upswing" and the results showed a “convenient coalescing around Biden across the board,” Ferson said.

Ferson added that voters in Massachusetts, at least, separated their feelings on Warren from their vote — meaning they largely still back her enthusiastically as a senator and leading voice on progressive issues, but those sentiments didn’t translate to enough votes against surges from both Biden and Sanders.

While Cignoli said there was “no positive spin” anyone could put on Warren’s “stunning” losses on Tuesday, he said the impact of Biden’s South Carolina victory were unexpected across the board and that the results were more of a matter of circumstances than strategy.

He noted that Biden spent incredibly small amounts of money campaigning in Massachusetts compared to Warren and former New York City Mayor Michael Bloomberg, and added that she had led or been competitive in polls less than two weeks ago.

“Any political consultant or pundit who tells you they’re not stunned is lying,” Cignoli said, adding that Biden staffers and supporters were were equally surprised.

Cignoli said the support from Clyburn, and in turn, African American pastors throughout the south, help “erupt” backing for Biden over the weekend.

“Uncle Joe, overnight, turned into Joe Cool," he said.

Cignoli described Warren as “a better public servant and better candidate than this process has allowed her to be." He said her “winning” debate performances decimated Bloomberg’s campaign but may have hurt her in unexpected ways, with fiery attacks that are typically reserved for corporate CEOs and Trump administration aides suddenly leveled at Democratic opponents Buttigieg and Klobuchar.

Neither consultant saw a path forward for Warren to seal the Democratic nomination.

“It’s a two-person race,” Ferson said, referencing Biden and Sanders.

Several progressives and Sanders surrogates called for her to exit the race.

Rep. Ilhan Omar of Minnesota on Tuesday said, “Imagine if the progressives consolidated last night like the moderates consolidated, who would have won? That’s what we should be analyzing."

Bloomberg, who ended his campaign on Wednesday, endorsed Biden, saying the Delaware Democrat was the best bet against Trump.

How much will Bloomberg’s support — in the form of staff and untold millions on advertising — help Biden in his third White House bid?

Ferson noted that, “As much as we might like to poke fun at Mike Bloomberg for the most expensive per-vote race in history of humanity ... we make fun at our own peril, because he’s got billions he can put some place. If he does use it to try to defeat Donald Trump, he gets a bust on Biden’s shelf just like Jim Clyburn.”
