(CNN)With 57 days until the Iowa caucuses, the 2020 election will be here before you know it. Every Sunday, I outline the 5 BIG storylines you need to know to understand the upcoming week on the campaign trail. And they're ranked -- so the No. 1 story is the most important of the coming week.

5. Mayor Pete under the microscope: It appears as though the rest of the Democratic field has -- finally -- woken up to the reality that if the Iowa caucuses and New Hampshire primaries were held tomorrow, South Bend Mayor Pete Buttigieg could very well win both.
While those facts have been clear for at least the last month, Buttigieg had been largely left alone by his rivals -- up to and including the November debate, in which no one this side of Hawaii Rep. Tulsi Gabbard was willing to offer any sort of sustained critique of the mayor.
No more. Late last week, Massachusetts Sen. Elizabeth Warren called on Buttigieg to make all of his fundraisers open to the press "so that anyone can come in and report on what's being said." And The New York Times editorial board provided Buttigieg's opponents with even more political ammo with an op-ed calling on Buttigieg to speak more openly about his time at McKinsey & Company, an elite consulting firm. (Buttigieg has said he is restricted from talking about his experiences at McKinsey because of a non-disclosure agreement -- and that he has asked to be released from the NDA, to no avail.)
What Buttigieg is about to go through is a rite of passage for any candidate who looks like a potential nominee. You simply don't get through a contested primary fight without your warts being examined. That's especially true for someone with Buttigieg's profile -- a 30-something mayor whose only experience in elected office is as the mayor of his hometown.
How Buttigieg navigates all the incoming he is beginning to face will be a telling indicator of whether he is a flash in the plan or someone who has the real potential to be the party's nominee next fall.
4. The Kamala coalition: It's easy to overestimate what the surprise departure of California Sen. Kamala Harris means for the Democratic race. After all, she rarely polled above mid-single digits and hadn't been a major factor in the contest since mid-summer at the latest. (Had she been more of a factor, she wouldn't have dropped out!)
But almost as soon as Harris was out, both New Jersey Sen. Cory Booker and former San Antonio Mayor Julián Castro were seeking to fill the void they perceived the California Democrat left.
"What message is that sending, that we heralded the most diverse field in our history, and now we're seeing people like (Harris) dropping out of this campaign?" asked Booker of Harris late last week in Iowa. Castro said that Harris had been held to a "double standard" by the media because she was an African American and Indian American woman.
While Booker and Castro are undoubtedly earnestly concerned about the reasons behind Harris' decision to leave the race, they are also motivated by politics here. As of today, only six Democrats have qualified for December debate -- and they are all white. (Much more on the debate below!) Booker and Castro are trying to use that lack of diversity to build momentum that has been sorely lacking in their own campaigns for months now.
Will it work? Probably not given that Harris wasn't a top-tier candidate when she dropped out of the race. But for candidates like Booker and Castro, who may be on the verge of being forced from the race, it's worth a shot.
3. Here comes Joe Biden!: Suddenly the former vice president is the hottest candidate in the race -- or at least a hot candidate in the race.
Biden's campaign announced in a memo last week that he had raised more than $15 million in October and November alone, more than he raised in the three previous months combined. He won the endorsement of 2004 Democratic nominee John Kerry, who will campaign with the former veep in New Hampshire this week. And, according to the Real Clear Politics polling average in the race, Biden has now reclaimed a double-digit lead over his nearest competitor.
How has Biden done it? Slow and steady-ish. He's never panicked -- even amid pans of his debate performances, poor fundraising and attacks from liberals on Twitter -- and stayed focused on his North Star: The African American vote. And black voters simply haven't wavered in their support of him -- nationally and in the critical early state of South Carolina.
Biden has also been aided by the unrelenting focus on both he and his son, Hunter, by the current resident of 1600 Pennsylvania Avenue. If Biden's strongest argument is that he is best-positioned to beat Donald Trump, then the President's fixation with Biden seems to suggest the incumbent is worried about him.
