The race for the Democratic presidential nomination is already heating up, even though there is almost a year to go before the Iowa caucuses.

Here are The Hill’s rankings of where the contenders stand right now.

1. Sen. Kamala Harris Kamala HarrisButtigieg stands in as Pence for Harris's debate practice First presidential debate to cover coronavirus, Supreme Court Harris joins women's voter mobilization event also featuring Pelosi, Gloria Steinem, Jane Fonda MORE (D-Calif.)

Harris has had by far the best launch of any candidate.

Her speech declaring her candidacy was delivered powerfully before a large and appreciative crowd in Oakland. Her appearances in early states have been well-received, as have her initial round of media interview. More generally, she has effectively presented herself as a fresh and charismatic presence.

Harris has also rolled out some early endorsements including Rep. Barbara Lee Barbara Jean LeeOvernight Defense: Pentagon redirects pandemic funding to defense contractors | US planning for full Afghanistan withdrawal by May | Anti-Trump GOP group puts ads in military papers Democrats call for investigation into Pentagon redirecting COVID-19 funds Steph, Ayesha Curry to be recognized by the Congressional Hunger Center MORE (D-Calif.) and, on Friday alone, both California Gov. Gavin Newsom (D) and Hispanic civil rights icon Dolores Huerta.

There are still plenty of questions that Harris will have to answer — including how her long record as a prosecutor will be scrutinized by a Democratic base focused on questions of police misconduct and racial inequities.

Early front-runners can easily come unstuck, but for now Harris is the most formidable candidate in the race.

2. Former Vice President Joe Biden Joe BidenOmar fires back at Trump over rally remarks: 'This is my country' Trump mocks Biden appearance, mask use ahead of first debate Trump attacks Omar for criticizing US: 'How did you do where you came from?' MORE

For all the excitement around Harris, it is the former vice president who still heads every significant nationwide poll of Democratic voters.

In an Emerson poll released on Saturday, he was 10 points ahead of his closest rival, Sen. Bernie Sanders Bernie SandersButtigieg stands in as Pence for Harris's debate practice Bernie Sanders warns of 'nightmare scenario' if Trump refuses election results Harris joins women's voter mobilization event also featuring Pelosi, Gloria Steinem, Jane Fonda MORE (I-Vt.), with Harris third, a further 2 points behind. A Morning Consult poll earlier last week put Biden 7 points clear of Sanders and 16 points ahead of Harris.

In 2016, Biden mulled a run for a long time before deciding against it. His son Beau had died from brain cancer in May 2015, and Biden ultimately chose not to force himself thorough the rigors of a presidential campaign.

This time around, The Hill has reported that he is almost certain to declare a candidacy soon.

Biden has weaknesses in the race, including his age — he would be 78 on Inauguration Day 2021 — and past votes that sit uneasily with the current Democratic base on everything from the Iraq War to a 1994 crime bill.

But his skills as retail politician, his experience and the loyal service he rendered for eight years to President Obama would all stand in his favor.

3. Sen. Bernie Sanders (I-Vt.)

Sanders entered the race early Tuesday, following weekend reports that he had recorded a video announcing his candidacy.

Sanders will clearly be a top-flight contender. Polls generally put him second, behind Biden.

He could end up being a victim of his own relative success in one sense, however. His stronger than expected challenge to eventual Democratic presidential nominee Hillary Clinton Hillary Diane Rodham ClintonButtigieg stands in as Pence for Harris's debate practice Senate GOP sees early Supreme Court vote as political booster shot Poll: 51 percent of voters want to abolish the electoral college MORE in 2016 showed there was an appetite in the party for more left-wing policies. Now, several other declared or likely candidates are running on progressive platforms that could blunt Sanders’s formerly unique appeal.

He has other problems as well, including the enmity he earned among Clinton supporters in 2016.

In January, he apologized to women who say they were harassed or mistreated by male staff during his 2016 campaign.

His decision to give his own rebuttal to President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE’s State of the Union speech aggravated some activists who believed he was taking the spotlight from the Democrats’ official speaker of the night, former Georgia gubernatorial candidate Stacey Abrams.

Age is an issue for Sanders, too. He is 77.

4. Former Rep. Beto O’Rourke (D-Texas)

Will he or won’t he?

That’s the key question around O’Rourke, who ignited enormous Democratic enthusiasm in his ultimately unsuccessful challenge to Sen. Ted Cruz Rafael (Ted) Edward CruzTrump argues full Supreme Court needed to settle potential election disputes Press: Notorious RBG vs Notorious GOP The Hill's Morning Report - Sponsored by Facebook - Washington on edge amid SCOTUS vacancy MORE (R-Texas) last year.

O’Rourke’s intentions are far from clear. He embarked on a road trip in January, earning some mockery from detractors for his introspective musings in an online diary.

On the other hand, when Trump held a rally in O’Rourke’s home base of El Paso recently, the former Texas congressman headlined his own event nearby, which drew a crowd several thousand strong.

The longer O’Rourke stays out of the race, the greater the danger that someone like Harris could really catch fire. On the other hand, his prodigious fundraising ability — he raised an eye-popping $38 million in 2018’s third quarter during his Senate bid — ensures he would be a serious candidate.

Previous ranking: 1

5. Sen. Elizabeth Warren Elizabeth WarrenHarris joins women's voter mobilization event also featuring Pelosi, Gloria Steinem, Jane Fonda Judd Gregg: The Kamala threat — the Californiaization of America GOP set to release controversial Biden report MORE (D-Mass.)

It’s been a largely uninspiring start to the campaign for Warren, who had been considered one of the leading candidates in the early running.

Part of the problem is the issue that won’t quit — her prior self-identification as a Native American and her decision last year to take a DNA test to prove that she was telling the truth.

The test affirmed that she had a Native American ancestor six to 10 generations ago. But even some Democrats believe the whole episode played into the hands of Trump, who continues to deride Warren, whom he has long mocked as “Pocahontas.”

Warren is betting that there is a strong electoral market for someone who can combine her professorial in-depth knowledge, especially of financial regulation, with a style that savors confrontation with Trump.

But her initial poll ratings are average at best, fueling suspicions that she is being overtaken by other figures, particularly Harris, who may have a stronger personal magnetism.

6. Sen. Cory Booker Cory Anthony BookerBipartisan praise pours in after Ginsburg's death DHS opens probe into allegations at Georgia ICE facility Democratic lawmakers call for an investigation into allegations of medical neglect at Georgia ICE facility MORE (D-N.J.)

Booker is one of the most recent entrants into the race — he announced on Feb. 1.

The New Jersey senator divides opinion, especially inside the Beltway. To his supporters, he is a likable, energetic candidate who speaks passionately and has the capacity to fire up young and nonwhite voters with particular vigor.

His detractors, however, assail him as an inauthentic lightweight, who has long been more interested in promoting himself than anything else. That critique stretches from his time as the Twitter-friendly mayor of Newark to his self-proclaimed “Spartacus moment” during the confirmation hearings of Supreme Court Justice Brett Kavanaugh Brett Michael KavanaughOvernight Health Care: US coronavirus deaths hit 200,000 | Ginsburg's death puts future of ObamaCare at risk | Federal panel delays vote on initial COVID-19 vaccine distribution Senate GOP sees early Supreme Court vote as political booster shot Trump says he'll make Supreme Court pick on Saturday MORE.

Booker will likely need to show he can get traction fairly soon, before the expected arrival of other big stars on the stage — including Biden — threatens to push him toward the margins of the race.

Previous ranking: 7

7. Sen. Amy Klobuchar Amy KlobucharSocial media platforms put muscle into National Voter Registration Day Battle lines drawn on precedent in Supreme Court fight Sunday shows - Ruth Bader Ginsburg's death dominates MORE (D-Minn.)

Klobuchar certainly had an eye-catching campaign launch — she gave a speech declaring her candidacy in the midst of a heavy snowstorm.

The visuals were memorable and underlined Klobuchar’s core message that she is a down-to-earth contender from the heartlands.

But that in itself won’t assuage the doubts about Klobuchar’s ultimate chances of success: Do Democrats really want someone who leans toward centrism as their standard-bearer against Trump?

Recent allegations that she mistreated staff have further complicated Klobuchar’s chances.

Some of the milder accusations against her carry more than a whiff of sexism, but it is harder to make that case when it comes to the most dramatic allegations, including one instance where she purportedly threw a binder that struck a staff member.

Previous ranking: 8

8. Sen. Sherrod Brown Sherrod Campbell BrownSenate Democrats release report alleging Trump admin undermined fair housing policies Bipartisan praise pours in after Ginsburg's death Emboldened Democrats haggle over 2021 agenda MORE (D-Ohio)

Brown has long been a political curiosity: a progressive Democrat who continues to win reelection in the increasingly red state of Ohio by wide margins.

Brown has been building up some momentum with a tour of early-voting states. But it is not clear he is getting into the race, and the likely entrance of Biden — who has a similar blue-collar appeal — would greatly complicate the Ohioan’s possible path to the nomination.

Previous ranking: 6

9. Sen. Kirsten Gillibrand Kirsten GillibrandSunday shows preview: Justice Ginsburg dies, sparking partisan battle over vacancy before election Suburban moms are going to decide the 2020 election Jon Stewart urges Congress to help veterans exposed to burn pits MORE (D-N.Y.)

Gillibrand launched her campaign in mid-January with an appearance on Stephen Colbert’s “Late Show” on CBS. Sadly for the New York senator, that’s the most memorable thing she has done so far.

Gillibrand always faced an uphill climb toward the nomination. There is nothing to suggest the gradient has become any less steep.

Previous ranking: 10

10. Former New York City Mayor Michael Bloomberg

Bloomberg continues to toy with a bid, but it is enormously difficult to see a credible route for the former New York City mayor, despite his vast fortune.

Bloomberg’s business-friendly centrism seems a poor fit for today’s Democratic Party, and he is far from a natural politician on the stump, which would hinder him in the early-voting states of Iowa and New Hampshire.

Previous ranking: 9
