“Amy Klobuchar had a stellar debate performance this week, she deserved a bounce this week, and she got one,” Progressive Change Campaign Committee co-founders Stephanie Taylor and Adam Green said. The group, which has endorsed Warren, noted that both women have finished ahead of Biden.

Warren, who has canceled more than $500,000 in ad reservations in South Carolina and about $60,000 in Nevada, will campaign in Virginia on Thursday and Nevada on Saturday, Sunday, Monday and next Friday. In a fundraising email Wednesday, Warren's team told supporters that Tuesday night “didn’t go the way we wanted it to go,” but, “Elizabeth has only taken the first steps of a marathon.”

In a Tuesday afternoon memo, Warren campaign manager Roger Lau made the case that the race was still “wide open” heading into New Hampshire.

“No candidate has come close yet to receiving majority support among the Democratic primary electorate, and there is no candidate that has yet shown the ability to consolidate support,” he wrote.

Though Warren has branded herself as the unity candidate, Lau took a “quick, sober look at the landscape of” her rivals’ challenges. He said Sanders’ ceiling is “significantly lower” than in 2016, Biden is fading, Buttigieg’s “most significant challenge is yet to come” as he faces a diverse electorate for the first time, and Klobuchar lacks infrastructure “for the long haul” and “is playing catch up on a very short timeline.”

The Quinnipiac poll showed Biden’s once-massive lead with black voters down to just 5 percentage points over former New York Mayor Michael Bloomberg, who announced endorsements Wednesday from Reps. Lucy McBath of Georgia and Gregory Meeks of New York and U.S. Virgin Islands Del. Stacey Plaskett.

But Bloomberg’s longtime support for the controversial policy of stop and frisk, which disproportionately impacted minorities, was thrust into the spotlight again Tuesday when President Donald Trump and his aides circulated leaked audio of what appeared to be blunt remarks from Bloomberg in 2015.

As the fallout metastasized, Bloomberg blamed Trump for being divisive and said his comments “do not reflect my commitment to criminal justice reform and racial equity.”

In South Carolina polls, Steyer has surged to second place and performed well with black voters. Steyer hired South Carolina state Rep. Gilda Cobb-Hunter, the longest-serving member of the statehouse and president of the National Black Caucus of State Legislators, as a senior adviser on Wednesday.

“Steyer is building the most racially diverse coalition of voters who look like America as it is today,” Cobb-Hunter told The Associated Press. “He is the only candidate who walks the walk and talks the talk.”

The conversation about the Democratic frontrunner made its way beyond Twitter and cable news and onto the Senate floor, where the No. 3 Senate Republican, John Barrasso of Wyoming, declared that “a socialist is now the frontrunner for the Democrat nomination for president.”

It even entered the Oval Office, where Trump was asked to weigh in on Wednesday afternoon.

“I would say Bernie looks like he’s doing very well,” Trump told reporters. “I think people like his message. He’s got energy. His people have energy. But they like his message, but a lot of people don’t like that particular message, but there is a group that probably agrees with it. And whoever it is, we’ll take them on, but it would certainly seem that Bernie Sanders has the advantage right now.”
