Washington(CNN) Author Marianne Williamson ended her 2020 Democratic presidential campaign on Friday after failing to gain traction in a crowded Democratic field.

"I stayed in the race to take advantage of every possible opportunity to share our message. With caucuses and primaries now about to begin, however, we will not be able to garner enough votes in the election to elevate our conversation any more than it is now," Williamson wrote in a message to supporters.

"The primaries might be tightly contested among the top contenders, and I don't want to get in the way of a progressive candidate winning any of them," Williamson continued.

Williamson pledged to fully support the Democratic nominee.

Williamson had not qualified for the Democratic debate next week. The spiritual author had laid off her campaign staff nationally, a former staffer confirmed to CNN last week.

After launching her campaign in January 2019, Williamson told CNN she was running to bring a "moral and spiritual awakening" for America.

"Nothing short of that is adequate to fundamentally change the patterns of our political dysfunction," Williamson told CNN's John Berman at the time.

Williamson's campaign has been little-noticed in recent months, as focus shifted to the Democratic contenders who were meeting the party's fundraising and polling thresholds to qualify for debates and Williamson repeatedly missed the cut.

Williamson, a native of Houston, attended Pomona College in California after graduating from high school. "In my mid-20s I began reading a set of books called 'A Course in Miracles,' " she says on her campaign website. "The 'Course' is not a religion, but rather a self-study program of spiritual psychotherapy based on universal spiritual themes. There is no dogma or doctrine; it is simply a book on how to forgive. I had no idea at the time that my study of the 'Course,' plus writing and speaking about it, would turn into a 35-year career."

But her campaign had attracted attention -- and admirers -- at times.

Williamson's most notable policy proposal was likely her call for at least $100 billion -- but potentially as much as $500 billion -- in reparations for the descendants of slaves. She said the money would be divvied up by a council of black leaders.

"America will not have the future we want if we're not willing to clean up the past," she said in a TV ad in South Carolina focused on the issue.

In summer 2019, she announced she was moving to Des Moines, Iowa. That meant she'd be on the ground full-time in the first state to cast votes in the nominating process.

In a debate in June, she said her first act as president would be to call New Zealand Prime Minister Jacinda Ardern and say, "Girlfriend, you are so on." Williamson's proclamation came as a response to an op-ed Ardern wrote last year, in which she said she wanted to make New Zealand the best place in the world to be a child.

She got attention in the following month's debate, too, when she said President Donald Trump had harnessed a "dark psychic force of collectivized hatred."

She chided her Democratic foes for rolling out policy proposal after policy proposal, saying she instead preferred to focus on ideas.

July was the last debate Williamson qualified for, though, and since that point, her campaign languished with little attention. Earlier this month, she announced she'd laid off her campaign staff but would continue on without it.
