Former White House Chief Strategist Stephen Bannon has reportedly lost the support of billionaire backer Rebekah Mercer after he suggested he might run for president himself.

A person close to Mercer told The Washington Post that she no longer supports Bannon. According to the report, Mercer was frustrated with Bannon's strategy in the Alabama Senate Race, and pulled her funding after he told other major conservative donors that Mercer would back Bannon in his own presidential bid.

Bannon supported GOP Alabama Senate Candidate Roy Moore, who was dogged by allegations of sexual misconduct, in his eventual defeat to Democratic challenger Doug Jones in December.

"The core constituency for Breitbart is what you would call the Trump Deplorables. That's the audience. And if they're asked to choose between Steve and Trump, they're going to choose Trump. That's clear," a person familiar with Breitbart News' operations told The Post.
