A former strategist for presidential candidate Donald Trump’s super PAC published a scathing open letter about the billionaire candidate that is going viral.

Stephanie Cegielski, a former strategist for the “Make America Great Again” super PAC, posted a lengthy letter on xojane.com Monday explaining why she went from being a full-time supporter to an opponent of the Republican front-runner.

In the letter, she says that even Trump’s closest advisers didn’t expect his success, and that his campaign was merely a “protest candidacy.”

My support for Trump began probably like yours did,” the letter reads. “Similar to so many other Americans, I was tired of the rhetoric in Washington. Negativity and stubbornness were at an all-time high, and the presidential prospects didn’t look promising.

In 2015, I fell in love with the idea of the protest candidate who was not bought by corporations. A man who sat in a Manhattan high-rise he had built, making waves as a straight talker with a business background, full of successes and failures, who wanted America to return to greatness.

I was sold.

She writes that over time she changed her views on Trump. She never expected him to do so well, and became disenchanted. Cegielski writes she was disappointed by his foreign policy and his failure to show empathy to the victims of the terror attacks in Belgium. Trump became more arrogant and isolated, according to the Cegielski’s letter, and her excitement about the campaign became anger.

What was once Trump’s desire to rank second place to send a message to America and to increase his power as a businessman has nightmarishly morphed into a charade that is poised to do irreparable damage to this country if we do not stop this campaign in its tracks.

I’ll say it again: Trump never intended to be the candidate. But his pride is too out of control to stop him now.

You can give Trump the biggest gift possible if you are a Trump supporter: stop supporting him.

He doesn’t want the White House. He just wants to be able to say that he could have run the White House. He’s achieved that already and then some. If there is any question, take it from someone who was recruited to help the candidate succeed, and initially very much wanted him to do so.

The hard truth is: Trump only cares about Trump.
