Elizabeth Warren was the punching bag in Tuesday (October 15) night's Democratic debate in Ohio.
Now that she's she's in a virtual tie with former Vice President Joe Biden, her 2020 rivals went on the attack.
And unlike past debates, Biden was mostly out of the line of fire.
Warren was grilled about healthcare by many of the 11 other candidates onstage.
She was forced to explain whether her plan would mean higher taxes for Americans.
Warren vowed she quote "would not sign a bill into law that does not lower costs for middle class families." Biden - as well as middle-of-the-pack names like Pete Buttigieg and Amy Klobuchar - painted Warren's plan as vague.
What did unify the candidates was that Donald Trump needed to go.
(SOUNDBITE) (English) U.S. SENATOR CORY BOOKER OF NEW JERSEY, SAYING: "We have to have a leader that can unify all Democrats, excite and engage the full breadth of our party to take on the biggest presidential challenge of our era." Most onstage voiced support for an impeachment inquiry of the president.
Biden and Bernie Sanders called Trump 'the most corrupt president in modern history." And many critiqued Trump's decision to pull U.S. troops out of Syria.
(SOUNDBITE) (English) U.S. SENATOR KAMALA HARRIS OF CALIFORNIA, SAYING: "Everyone needs to be clear about what this is, Donald Trump represents a real national security threat to the United States of America.
And this is yet another example of that.
The three candidates leading in the polls - Warren, Biden and Sanders - were also all asked about age.
Sanders reassured voters he was fighting fit after a heart attack two weeks ago.
News also broke Tuesday night Sanders will get endorsements from two high-profile progressives: Alexandria Ocasio-Cortez and Ihan Omar.
Ocasio-Cortez plans to appear with Sanders at a rally in Queens, New York on Saturday (October 19).
