LEADING THE DAY:

Impeachment politics have consumed Washington, pushing the race for the Democratic primary to the back burner as insiders debate the political fallout of the historic event gripping the nation.

The two parties are placing competing bets. For Democrats, it's that the budding impeachment inquiry in the House will yield a clarifying moment for the country that will prompt voters to overwhelmingly reject President Trump Donald John TrumpFederal prosecutor speaks out, says Barr 'has brought shame' on Justice Dept. Former Pence aide: White House staffers discussed Trump refusing to leave office Progressive group buys domain name of Trump's No. 1 Supreme Court pick MORE, who is accused of using the power of his office to pressure a foreign government to investigate one of his chief political rivals.

Meanwhile, Republicans are betting that the impeachment episode will look less like 1974, when President Nixon resigned in disgrace, and more like 1998, when a Republican-led effort to impeach President Clinton backfired and Democrats picked up five House seats in the midterm elections.

The winning bet is still unknown, but what's clear is that the fast-moving controversy surrounding Trump's efforts to pressure Ukrainian President Volodymyr Zelensky to investigate former Vice President Joe Biden Joe BidenFormer Pence aide: White House staffers discussed Trump refusing to leave office Progressive group buys domain name of Trump's No. 1 Supreme Court pick Bloomberg rolls out M ad buy to boost Biden in Florida MORE for alleged corruption has left no facet of the 2020 election cycle untouched.

For Biden in particular, the controversy is something of a double-edged sword.

On one hand, it has elevated his argument that he poses the greatest threat to Trump's reelection bid and offers an opportunity to go head to head with the president.

But there are also fears among Biden's allies that the Ukraine controversy could weigh down his campaign and raise doubts among some voters about his character and record. Trump has repeatedly suggested that Biden withheld aid money to Ukraine while he was vice president to pressure officials in Kiev to fire a prosecutor investigating a company that Biden's son Hunter Biden was working for.

To be sure, there is no evidence of wrongdoing by the Bidens and the president's claims remain unsubstantiated. But some Democrats worry that by merely raising such allegations, Trump may be successful in sowing doubts in Biden among voters. As one Democratic strategist told The Hill's Jonathan Easley and Amie Parnes this week: "I think the big fear for Biden is that this turns into Hillary's email controversy. They took a big nothingburger and made it into something."

Still, a handful of Trump allies pointed to Biden as the biggest threat to the president, arguing that he's the only Democratic candidate capable of matching Trump punch for punch in a general election match-up.

Warren's rise has shaken up the Democratic field, write The Hill's Amie Parnes and Niall Stanage. Warren is expanding her campaign into states and districts with tight congressional races, according to The Hill's Tal Axelrod, coupled with a massive 8-figure digital and TV ad buy in the early voting states.

The Democratic National Committee (DNC) has hinted for weeks that it was on the verge of raising the thresholds to qualify for its November presidential debate. Those new criteria finally came on Monday. To qualify for the fifth debate, candidates will have to collect contributions from 165,000 unique donors and register at least 3 percent in four DNC-approved polls or 5 percent in two approved early-state polls, The Hill's Max Greenwood reports. The tougher requirements are likely to irk some lower-tier campaigns who have already struggled to make it into earlier debates. But the increased thresholds are more modest than some campaigns predicted, and nearly a dozen candidates have already met the donor requirement.

MONEY WATCH:

DEADLINE ALERT: We're three days away from the end of the third fundraising quarter of 2019, and campaigns are in a full-on sprint to secure last-minute donations. But one fundraising pitch that stands out from the pack is from Sen. Cory Booker Cory Anthony BookerThe movement to reform animal agriculture has reached a tipping point Watchdog confirms State Dept. canceled award for journalist who criticized Trump 3 reasons why Biden is misreading the politics of court packing MORE (D-N.J.), whose campaign warned supporters and journalists last weekend that he would almost certainly drop out of the presidential primary unless he's able to raise $1.7 million before Sept. 30.

Booker's allies insist that the warning isn't just a clever fundraising ploy. Without that money, they say, the New Jersey senator won't be able to scale up his campaign in the way he needs to stay competitive. But at the same time, his campaign manager Addisu Demissie told reporters that Booker hasn't running out of money – and isn't even at risk of doing so. What's more, Booker has already qualified for the fourth primary debate in October, and it's unlikely that he would exit the race before then.

Either way, the appeal for money appears to be paying off. In a matter of four days, Booker had hit the $1 million mark, putting him on track to reach his goal before the Monday fundraising deadline.

Meanwhile, former Housing and Urban Development Secretary Julián Castro says he'll end his campaign if he doesn't meet the new fundraising and polling metrics for the November debate (The Hill).

Great America PAC, a super PAC backing Trump's reelection bid, rolled out a new TV ad on Wednesday urging Congress to investigate Biden's role in the firing of a former Ukrainian prosecutor, The Hill's Jonathan Easley reports. The spot, which is running online and on Fox News, marks an outside effort by conservatives to train attention on the former vice president and away from allegations that Trump used his office to pressure Ukrainian officials to investigate Biden.

POLL WATCH:

SUFFOLK: Biden edges out Warren by nearly 4 points in Nevada, registering at 23.2 percent support. Sanders, meanwhile, comes in third place with 14.2 percent in the early caucus state. Harris and Buttigieg lagged well behind the three top contenders, receiving 3.8 percent and 3.4 percent support, respectively.

MONMOUTH: Warren tops Biden 27 percent to 25 percent among registered New Hampshire Democrats and unaffiliated voters who are likely to vote in the crucial first-in-the-nation primary. Only two other candidates, Sanders and Buttigieg, registered double-digit support (12 percent and 10 percent, respectively). Harris finished in a distant fifth place with 3 percent support.

DES MOINES REGISTER/CNN: The landmark Iowa poll shows Warren pulling into first place with 22 percent support among likely Democratic caucusgoers, while Biden fell to second place with 20 percent support. Rounding out the top five: Sanders (11 percent), Buttigieg (9 percent) and Harris (6 percent).

HARVARD CAPS/HARRIS: Biden holds a double-digit lead against his closest rivals, but there are signs Biden's support may be slipping.

ONE FUN THING

OUTSIDER: Political outsiders have dominated the news cycle over the past four years -- whether it's President Trump's successful foray into politics after a long business career, or Rep. Alexandria Ocasio-Cortez Alexandria Ocasio-CortezOn The Money: Anxious Democrats push for vote on COVID-19 aid | Pelosi, Mnuchin ready to restart talks | Weekly jobless claims increase | Senate treads close to shutdown deadline McCarthy says there will be a peaceful transition if Biden wins Anxious Democrats amp up pressure for vote on COVID-19 aid MORE's (D-N.Y.) fresh, progressive ideas that took her from Queens bartender to congresswoman.

However, one Florida woman wants to give new meaning to the term political outsider through electing a turtle to be mayor of Clearwater.

No, I'm not joking.

Elizabeth Drayer says she wants a sea turtle to be elected mayor of the city so nature can be given a voice, according to The Tampa Bay Times.

The only issue with the plan is that city rules say that only registered voters who reside in Clearwater are eligible to run for mayor -- meaning there aren't any turtles who made the cut.

So Drayer is throwing her name in the ring -- and running as "Elizabeth 'Sea Turtle' Drayer."

And just so we're clear, she's not accepting any financial contributions.

"The sea turtle cannot be bought," she said.

On that note -- we'll see you next week for the latest campaign news!
