The outcome of the first two contests in the primary calendar have resulted in a splintered moderate field and Sanders emerging as the favorite candidate for the party's progressive camp.

Bloomberg's presence in the race has raised concerns that a four-way fight for the moderate vote will mean no centrist alternative emerges to Sanders, leading to a long slog to the nomination that leaves Democrats with little time to unify before taking on President Trump Donald John TrumpObama calls on Senate not to fill Ginsburg's vacancy until after election Planned Parenthood: 'The fate of our rights' depends on Ginsburg replacement Progressive group to spend M in ad campaign on Supreme Court vacancy MORE in November.

“At the moment, they’re cannibalizing each other,” Democratic strategist Jon Reinish said. “You have no one who can really emerge while they’re all taking votes from each other.”

The splintering of the moderate vote is diluting the impact of centrist Democrats.

Klobuchar and Buttigieg together carried 44.2 percent of the vote in the New Hampshire primary, far outpacing Sanders’s 25.7 percent share of the vote. Even with Sen.

Both candidates are now moving full steam ahead to Nevada, which holds its caucuses on Feb. 22. Buttigieg’s campaign announced this week it was expanding its staff on the ground to 100, while Klobuchar’s campaign has deployed 50 staffers to the state. Both campaigns have also unleashed ad buys in Nevada.

The two, along with Biden, have also sniped at each other in recent weeks. Klobuchar hit Buttigieg on the debate stage in New Hampshire last week, saying that while she and other 2020 senators were taking part in the impeachment trial, Buttigieg “wanted to turn the channel and watch cartoons.”

Meanwhile, Biden hit Buttigieg in an ad last week, suggesting that the former mayor does not have enough experience to be commander-in-chief.

Democratic moderates will also have to contend with as ascendant Bloomberg, who has spent hundreds of millions of dollars in an advertising blitz.

“Given this sort of three-way cannibalization that’s going on at the moment, that’s making a lot of people very nervous and increasingly folks are looking around the room, and eyes are lighting on Mike Bloomberg,” Reinish said.

The splintered moderate votes could lead to Sanders reaping the benefits, after poor showings by Warren in Iowa and New Hampshire have made him the progressive candidate standard bearer.

“I think there’s definitely enough room to go around,” South Carolina Democratic strategist Antjuan Seawright told The Hill, referring to the moderate lane. “But it also leaves a wide lane for the other wing of the party to zap up energy and support as this race comes on.”

Sanders has long raised concerns among segments of the Democratic party, who worry the self-described Democratic socialist is too liberal to beat Trump in November.

“We are running the risk of the possibility of a standard bearer who doesn’t represent where voters are and who is ill-equipped to take on Donald Trump, and who is ill-equipped to lead Democrats to down-ballot success,” Reinish said.

Other Democrats worry that a crowded field where no single candidate emerges as the front-runner could lead to a brokered contest at the Democratic National Convention in July.

“There's no doubt about it that we are headed possibly to a brokered convention,” Moe Vella, a former Biden adviser who sits on the board of Transparent Business, told The Hill. “A brokered convention could be damaging to the moderate, centrist, pragmatic left.”

Campaigns, however, have played down divisions between centrist and progressive camps, saying voters are showing cross-over interest in their preferences.

“There are Warren-Klobuchar voters. There are Biden-Bernie voters. There are Bernie-Pete voters, and there are obviously Biden-Pete voters, and Biden-Klobuchar voters,” a campaign aide to one of the moderate candidates told The Hill. “You just need to look at this more or so as who is presenting the best vision, and what type of non-ideological are people making."

However, strategists argue the fear of a divided party is a reality and say an ideal candidate would seek to unite the progressive and centrist camps within the party even as voters struggle to pick who among the current field fits that description.

“They’re looking at who can bring not only the country together, but the party back together,” Seawright said. “The candidate who occupies that centrist lane, but knows how to drive their car over when needed to the progressive lane, has a better chance of controlling the entire highway when this process is over.”

“No matter how it plays out, we’re going to have to pull the voters on both sides of the highway back together,” he added.
