LEADING THE DAY: Debate stage expected to get a little smaller as deadline looms

It's deadline day, and the Democratic debate stage is expected to get a little bit smaller.

The White House hopefuls have until midnight to hit 5 percent support in four national polls or 7 percent support in two early-state polls to qualify for the Jan. 14 debate in Des Moines, Iowa, which takes place only weeks before voters in the Hawkeye State gather for the first-in-the-nation caucuses. Candidates also must have received donations from 225,000 unique donors.

Here is who has qualified so far:

There have been a raft of early-state polls released in the past 24 hours, and we know of at least one more big qualifying survey that's coming later in the day from the Des Moines Register, largely considered the gold standard in Iowa polling.

But in all likelihood, tech entrepreneur Andrew Yang Andrew YangDoctor who allegedly assaulted Evelyn Yang arrested on federal charges The Hill's Campaign Report: Biden weighs in on police shootings | Who's moderating the debates | Trump trails in post-convention polls Buttigieg launches his own podcast MORE's debate run will come to an end, at least for now. Yang has blown past the fundraising threshold, bringing in an astonishing $16.5 million in the fourth quarter. But he has hit only one qualifying survey, and it seems unlikely he will be able reach the higher bar for polling by the end of the day.

If you're scratching your head as to how Steyer managed to make it back to the debate stage, you're not alone.

Steyer, a billionaire who has pumped tens of millions of dollars into his own campaign, announced last week that he hit the donor threshold. But he has been languishing in the low-single digits in most polls and appeared poised to miss the cut until a couple of shocking surveys released last night found him surging in South Carolina and Nevada.

A Fox News survey of Nevada found Steyer jumping by 7 points and pulling into a third place tie with Warren at 12 percent support. And a separate Fox News poll of South Carolina found Steyer surging into second place with 15 percent support, a jump of 11 points from October.

Are the surveys outliers or do they reflect how effective it can be to spend tens of millions of dollars in Nevada and South Carolina, the third and fourth states to vote, while your rivals are focused almost exclusively on Iowa and New Hampshire?

It's unclear at this point, but we know this much -- billionaire cash has completely upended the Democratic primary.

According to data from Advertising Analytics, Steyer has spent $67 million on the airwaves so far, more than the rest of the Democratic field combined, with the exception of former New York City Mayor Michael Bloomberg Michael BloombergTop Democratic super PAC launches Florida ad blitz after Bloomberg donation The Hill's 12:30 Report - Presented by Facebook - Latest with the COVID-19 relief bill negotiations The Memo: 2020 is all about winning Florida MORE, a fellow billionaire who has spent more than $150 million of his own money on campaign ads.

FROM THE TRAIL:

It's been a head-spinning week on the foreign policy front, as turmoil in the Middle East has the Democratic White House hopefuls facing a commander-in-chief test with the Iowa caucuses less than a month away. President Trump Donald John TrumpHR McMaster says president's policy to withdraw troops from Afghanistan is 'unwise' Cast of 'Parks and Rec' reunite for virtual town hall to address Wisconsin voters Biden says Trump should step down over coronavirus response MORE's authorization last week of a drone strike that killed an elite Iranian general in Iraq touched off a heated debate among the Democratic presidential candidates over foreign policy, Julia reports. While the field of hopefuls was largely united in condemning the strike as having imperiled U.S. national security, the topic also threatened to dredge up memories of the Iraq War and the 2002 vote to authorize the use of force there.

Sanders, in particular, hasn't pulled any punches against Biden in the foreign policy debate, Max reports. He's attacked the former vice president in recent days over his initial support for the war in Iraq, accusing him of helping lead the U.S. into "the most dangerous foreign policy blunder in the modern history of this country." But Biden has sought to use the recent drone strike in Iran to talk up his foreign policy credentials and relationships with world leaders.

Joe Biden is running a general election campaign in the middle of a primary. Unlike most of his rivals for the Democratic presidential nomination, the former vice president's rhetoric and campaign strategy have hewed more towards courting centrists and independents instead of the liberal base that typically carries the most influence in primary contests, The Hill's Amie Parnes reports. It's an unusual strategy, but one that appears to be working for Biden. He's managed to hold on to his frontrunner status for months, despite a series of uneven debate performances and criticism from the Democratic Party's ascendant progressive wing.

FROM CONGRESS AND THE STATES:

Republicans are playing defense in this year's race for the Senate, but Democrats likely have a tough fight ahead in their bid to take control of the chamber. Max has a look at the five most vulnerable senators up for reelection. Four of them are Republicans...

In total, James raised $3.5 million in the final three months of the year, while Peters raked in about $2.5 million. The fundraising haul is likely to buoy Republicans' hopes of ousting Peters in 2020. Still, Peters has raised more throughout the campaign cycle, bringing in about $9.3 million in 2019 compared to James's $8 million. And despite Trump's victory in Michigan in 2016, the state appears to be shifting back in favor of Democrats.

Detroit News poll: Peters has a small lead over James.

ONE FUN THING:

THE PERRY FACTOR: Hollywood political circles were abuzz this week after People Magazine reported on Thursday that popstar Katy Perry dined with Michael Bloomberg at Wolfgang Puck's CUT in the Beverly Wilshire hotel.

The publication reports that Perry chatted about her candidate and policy preferences at the dinner, which was also attended by her friends.

Perry has not endorsed Bloomberg, whose campaign told People that they "don't confirm private meetings.

The singer has never been shy about her political views and had a ringside seat during the 2016 presidential campaign.

She even took over Clinton's Instagram in 2015 and dressed up as the candidate for Halloween in 2016.

While we don't know of any plans for Perry to endorse Bloomberg, we do know that the former New York City mayor did score one notable celebrity endorsement this week.

Judge Judy Sheindlin, commonly known as Judge Judy, ruled in favor of Bloomberg this week, telling CNN that she believed he was the only candidate capable of defeating Trump.
