POWER RANKING: Here's who has the best chance of becoming the 2020 Democratic presidential nominee

8: Rep. Tulsi Gabbard of Hawaii Reuters Gabbard has some serious viability problems among Democrats. Not only do a significant proportion of respondents in Insider polling say they are unhappy with her as the nominee compared with her rivals, but Gabbard has not been able to consolidate support in a meaningful way. Despite being one of the first to enter the race, Gabbard is still polling at 1% in Morning Consult and is considered a less viable opponent to President Donald Trump in the general election than most other candidates. Gabbard has been barely been a factor in the 2020 primary contests that have taken place so far, getting just 0.19% of the vote in the second alignment at the Iowa caucuses, and 3.2% of the vote in New Hampshire.

7: Tom Steyer Associated Press Steyer achieved billionaire status as an investor and hedge fund manager - but he has since focused his efforts on advancing Democratic causes with two organizations, Need To Impeach and NextGen America. But after spending a huge chunk of his $1.6 billion fortune on his presidential campaign, Steyer still has largely failed to articulate a clear rationale for his candidacy and hasn't won any delegates yet. Steyer earned just 0.24% of the vote after the second alignment in the Iowa caucuses, and got just 3.5% of the vote in New Hampshire, where he spent nearly $20 million on ads. Still, Steyer could fare better in the Nevada caucuses and South Carolina primary, two states where he's poured millions into ads and has reached double-digits in some polls. But if he doesn't start winning delegates soon, Read more about Tom Steyer's campaign.

6: Sen. Elizabeth Warren of Massachusetts Associated Press Warren is the best-known candidate who has not previously run for president, and she has proved herself to be a top-tier candidate. She overlaps considerably with Sen. Bernie Sanders and Biden's bases, with half of Biden supporters and 57% of Sanders supporters also being satisfied with her as the nominee in Insider polling. But Warren's pitch as a unity candidate and the perfect medium between Biden and Sanders failed to pan out in the first two voting states. Despite a strong third-place finish in the Iowa caucuses, where she earned eight pledged delegates, Warren came in a disappointing fourth place with only 9% of the vote and no delegates in New Hampshire, her neighboring state. While the race is still in flux and her chances could improve, Warren's failure to perform well in two states where the electorate is particularly well-suited to her in being disproportionately white, college-educated, and liberal is a foreboding sign for the future.

4: Former Vice President Joe Biden Associated Press For his entire campaign, Biden's core argument has been that given his stature as a former vice president and his widespread appeal to voters of all stripes, he is the best position to defeat Trump in a general election. For a while, the strategy was a smart bet, given that Democratic primary voters routinely rank nominating a candidate who can beat Trump above all else. But to be successful, it relies on Biden actually winning elections. In Iowa, Biden trailed three of his opponents, earning just 13.7% of the statewide vote and 16% of state delegate equivalents, and coming in seven percentage points behind third-place finisher Elizabeth Warren. He fared even worse in New Hampshire, coming in fifth place with just 8.3% of the statewide vote. It's too early to count Biden out completely because of his lead among African-American, older, and non-college educated voters, which gives him an edge in Southern primary states including South Carolina. But the extremely fluid and unpredictable nature of the Democratic field, especially Michael Bloomberg's significant rise in support among black voters, means winning those voters and states is not a guarantee for him.

3: Michael Bloomberg Associated Press Bloomberg has the luxury of being able to self-fund his campaign with his estimated $60 billion net worth, and is seriously shaking up the presidential race. Bloomberg is sitting out the first four primary contests altogether and will try to rack up victories in the 15 Super Tuesday states, which all vote March 3 and account for 35% of the total pledged delegates allocated throughout the process. Leaving other candidates to fight over the first four states, which only hold about 4% of delegates, has allowed Bloomberg to stay above the fray and build critical infrastructure and in-roads in later delegate-rich places. Bloomberg has already made a pretty sizable impact. So far, he's spent a mind-boggling sum of at least $300 million on his campaign, including ads and has over 2,000 staff on his payroll, dwarfing his fellow candidates' spending by tens of millions of dollars. If you've watched TV or YouTube recently, you've probably seen multiple Bloomberg ads, and his aggressive strategy is paying off, rocketing him into the top tier of candidates. Bloomberg has shot up to third place nationwide in Morning Consult at 17%, is at 16% in Super Tuesday states, and has an average of 14.2% in Real Clear Politics' national polling average, earning him the third spot in our ranking.
