WASHINGTON — Nearly the entire Democratic presidential field will be stopping by the Iowa State Fair (and its famed fried foods and Butter Cow) over the next few days.

It’s a good reminder that — no matter what’s going on at a national level — it will be Iowa Democrats who deliver the first real results of the 2020 election when they caucus on February 3.

Here’s what we know about the landscape in Iowa so far (with more than 175 days to go).

Joe Biden leads, but Elizabeth Warren is gaining ground fast: A new Monmouth poll of Iowa out yesterday showed Biden still leading among likely caucus-goers at 28 percent support, and Warren jumping by double digits into second place at 19 percent. Harris is third at 11 percent, with Sanders slipping to fourth at 9 percent. Obviously, it’s just a single poll, but it mirrors what we’ve seen in national surveys lately, too: Biden is holding steady after the first two debates, and Warren is closing the gap and enjoying the highest favorability rating in the field.

Cory Booker is leading the endorsement race: Per our team on the ground in Iowa (NBC’s Maura Barrett, Priscilla Thompson and Ethan MacCumber), Cory Booker has the support of more than 40 Iowa elected officials and key activists, leading the rest of the pack by a pretty comfortable margin. But that backing hasn’t yet translated into statewide polling yet; the Monmouth poll found him with just one percent support.

Kamala Harris and Tom Steyer are going big on ads early: As NBC’s Deepa Shivaram reported yesterday, Kamala Harris is the first top-tier candidate to hit the TV airwaves in Iowa, reserving close to $200,000 for a 60-second ad running until August 14. According to the ad trackers at Advertising Analytics, the only other candidate with future TV time scheduled is Tom Steyer, who’s booked $386,000 through early next week. And the only other candidate who’s spent significantly on TV time so far in the state is John Delaney.

The candidates spending the most time on the ground in Iowa aren’t necessarily seeing dividends — yet: Our Iowa team also reports that the candidate who’s appeared at the most individual events in Iowa (over 170!) is Delaney —although he’s been in the race since summer 2017, more than a year before any other candidates. Also toward the top of the list are Beto O’Rourke (at least 67 individual events), Andrew Yang (66) and Amy Klobuchar (56). But so far, none of those candidates are seeing that time translated into a top-tier spot in polls.

The virtual caucus is still a big question mark: This cycle, for the first time, the Iowa Democratic Party will host six virtual caucuses, which means that participants won’t have to go in person to their designated caucus sites. But so far, it seems that voters aren’t sure at all how the process will work, and campaigns are still trying to figure out how to target those who might participate. (Not to mention it’s also a big challenge for pollsters trying to get their samples right.)

A word of caution: Reading into Iowa polls this early might turn out to be just spinning our wheels, so take it all with a Butter Cow-sized grain of salt.

Hillary Clinton’s dominance in 2016 Iowa polling wasn’t seriously in question until two months before the caucuses; the last Iowa GOP winner, Ted Cruz, mostly ran behind Donald Trump in public polling all the way until the caucus; and 2012 caucus winner Rick Santorum didn’t lead in a single Iowa poll in the run-up to his victory.

What’s next on guns?

It’s looking more clear that there’s sufficient pressure on the White House and Congress to pass some kind of gun legislation.

But what shape that takes is still a big unknown — and it pretty much comes down to the president.

During an interview on a Kentucky radio program, Mitch McConnell signaled that he’s open to considering background check legislation along with possible “red flag” bills, acknowledging that “there is a lot of support for that.” And he said this: “[W]hat we can't do is fail to pass something. By just locking up, and failing to pass, that's unacceptable.”

Meanwhile, Trump tweeted this morning that “Serious discussions are taking place between House and Senate leadership on meaningful Background Checks.” And/but: He also acknowledged that he’s been talking to the NRA, which made clear again yesterday where it stands on this.

(One thing about the NRA worth noting: With their current financial problems, this is probably a fight that they want — to fire up their members and reengage their donors.)

At the end of the day, whatever Trump’s willing to sign is what Republicans will try to do on the Hill. And the fact that they’re open to discussing background checks at all shows just how much pressure they’re feeling.

By the way, the White House is set to meet today with officials from tech companies including Facebook, Google and Twitter to discuss the rise of extremism online. But as the Washington Post writes, there’s lots of skepticism that the president’s taking that effort all that seriously.

Confronting corruption is a winning 2020 issue. But neither party has it locked down.

Concern about political corruption may not be a central issue every day on the 2020 campaign trail, but it’s a thread that runs through Democratic candidates’ criticisms of Trump’s business dealings, their lamenting of money in politics, and their rejection of super PACs.

And it’s still sort of a talking point for Trump, whose “Drain the Swamp” call resonated with swing voters in 2016. (Although we wonder what those voters think of his recent comments about a potential commutation for former Illinois Gov. Rod Blagojevich.)

So… who’s winning on this issue for 2020?

Democratic-affiliated group End Citizens United argues that neither party has won the argument with voters.

A poll of likely 2020 voters in 12 battleground states, conducted by Global Strategy Group on behalf of End Citizens United, found that “cracking down on political corruption” was a top priority for 83 percent of voters — right up there with health care affordability. But here’s how a series of messages tested when it came to which party is more trusted to take on the problem:

“Cracking down on political corruption”z

30% trust Democratic presidential candidates more

31% trust Trump more

39% neither/don’t know

“Limiting the influence of money in politics”

27% trust Democratic candidates more

26% trust Trump more

47% neither/don’t know

“Draining ‘the swamp’ in Washington”

27% trust Democratic candidates more

35% trust Trump more

38% neither/don’t know

That’s sure a lot of “pox on both their houses” voters — or at least ones who aren’t confident that the Democratic field is addressing this issue adequately.

But if one party can win over voters on this between now and November, it could make a significant difference up and down the ballot box.

Tweet of the Day

Dispatches from NBC’s embeds

While in Iowa, Sen. Elizabeth Warren was asked what would happen to individuals who are working in the private insurance industry under her Medicare for All plan, NBC’s Benjamin Pu reports: “Warren said that some people would be hired by the federal government to help administer the Medicare for all program, saying: ‘A lot of pieces to move but we can make it work.’”

Pete Buttigieg, Sen. Bernie Sanders, Sen. Booker and Gov. Bill Weld addressed black journalists in Miami. NBC’s Gary Grumbach reports: “Vermont Sen. Bernie Sanders was received warmly by the crowd of journalists here at NABJ. Sanders was clearly in a good mood, joking around with event moderators including NBC’s Craig Melvin about the always awkward ‘do I sit or stand while answering questions’ decision. … Even thought it was a room of journalists, New Jersey Sen. Cory Booker was a clear favorite, receiving numerous rounds of applause for lines on criminal justice reform and white supremacy.”

Data Download: The number of the day is… nine

Nine.

That’s the number of Democratic candidates who appear to have qualified for the September debate — so far — after yesterday’s Monmouth University Iowa poll gave Andrew Yang the support he needed to make the cut.

The others who have qualified to date, per a tally by NBC’s Ben Kamisar: Joe Biden, Cory Booker, Pete Buttigieg, Kamala Harris, Amy Klobuchar, Beto O’Rourke, Bernie Sanders and Elizabeth Warren.

Reminder: In order to qualify, candidates need to hit 2 percent in at least four qualifying polls, and they have to raise money from 130,000 unique donors.
