Sen. Elizabeth Warren has overtaken 2020 rival Joe Biden in Iowa to snatch the lead in a Des Moines Register/CNN/Mediacom Iowa Poll of preferred Democratic presidential candidates published Saturday night.

Why it matters: Per the Des Moines Register, this is the first time Warren has led in the state's poll. It's the latest in a series of surges in the polls for the Massachusetts senator. She's also been drawing big crowds in recent weeks.

  • Warren drew her largest campaign rally crowd of the 2020 cycle last Monday, when more than 20,000 people flocked to see her at Washington Square Park in New York City.

By the numbers: The poll of 602 likely Democratic caucusgoers was conducted Sept. 14-18, with a margin of error of plus or minus 4 percentage points. 22% of those polled say Warren is their pick for president. Former Vice President Biden is second with 20% and Sen. Bernie Sanders is the next closest at 11%.

Yes, but: While Warren and Biden appear to have pulled away from the rest of the Democratic presidential pack in Iowa, 63% of those polled said they could still change their mind after picking a top choice. Just 20% said they were decided on a first-choice candidate.

The big picture: Warren surged to the top of the Iowa poll as she joined 16 other Democratic presidential candidates at the state's annual Polk County Steak Fry in Des Moines, which drew a crowd of more than 12,200, according to the organizers, the Polk County Democrats.

  • Warren won the biggest applause at the event, for reiterating her call for President Trump to be impeached, the New York Times reports.

Trump tightens screws on ByteDance to sell Tiktok

President Trump added more pressure Friday night on China-based TikTok parent ByteDance to exit the U.S., ordering it to divest all assets related to the U.S. operation of TikTok within 90 days.

Between the lines: The order means ByteDance must be wholly disentangled from TikTok in the U.S. by November. Trump had previously ordered TikTok banned if ByteDance hadn't struck a deal within 45 days. The new order likely means ByteDance has just another 45 days after that to fully close the deal, one White House source told Axios.

In her first sit-down interview since being named Joe Biden's running mate, Sen. Kamala Harris talked about what she'll do to fight for women if elected VP, and how the Democrats are thinking about voter turnout strategies ahead of November.

What they're saying: "In a Biden-Harris administration women are going to be a priority, understanding that women have many priorities and all of them must be acknowledged," Harris told The 19th*'s Errin Haines-Whack.
