“People are gonna think that I’m trolling but compared to what else is up on this stage I think Marianne Williamson is actually winning this thing,” Trump Jr. tweeted during the debate. “This is amazing. No question she seems to be drawing the biggest applause of the night.” 

Williamson had a memorable appearance Tuesday night with some top moments from the showdown, including her taking aim at President TrumpDonald John TrumpO'Rourke: Trump driving global, U.S. economy into recession Manchin: Trump has 'golden opportunity' on gun reforms Objections to Trump's new immigration rule wildly exaggerated MORE’s administration by calling out a “dark psychic force” emanating from the White House.

"If you think any of this wonkiness is going to deal with this dark psychic force of the collectivized hatred that this president is bringing up in this country, then I’m afraid that the Democrats are going to see some very dark days," Williamson said.

The self-help author also called out her fellow 2020 Democrats on taking money from corporate donors.

“For politicians, including my fellow candidates who themselves have taken tens of thousands and, in some cases, hundreds of thousands of dollars from these same corporate donors, to think that they now have the moral authority to say, ‘We’re going to take them on,’ I don’t think the Democratic Party should be surprised that so many Americans believe ‘yada, yada, yada,’” she said, prompting applause from the audience.

And when asked about tuition-free college, Williamson — who supports eliminating student debt — slammed people who “think there’s something wrong about using the instruments of government to help people.”

“I almost wonder why you’re Democrats,” she said. “You seem to think there’s something wrong about using the instruments of government to help people. That is what government should do. All policies should help people thrive. That is how we will have peace and that is how we will have prosperity.” 

Williamson was the most searched candidate during Tuesday night's Democratic debates, according to Google Trends.
