Donald Trump took to Facebook today to suggest a move that would all but end Hillary Clinton’s hopes for the White House.

“Bernie Sanders has been treated terribly by the Democrats–both with delegates & otherwise,” Trump wrote. “He should show them, and run as an Independent!”

Back in September, author Ed Klein reported “insiders” with the Bernie Sanders campaign said the socialist senator was “poised” to run as a third-party candidate.

“Several Sanders campaign insiders say the 73-year-old leftwing firebrand is convinced the fix is in to give the Democrat nomination to Hillary—unless she implodes, at which point the party will line up lockstep behind Biden,” according to Klein.

The Sanders campaign sources believe he would be able to trump Hillary’s and Biden’s money, ground game and endorsements.

“In Bernie’s opinion Hillary is owned by Wall Street and is a hawk,” says one of Sanders’ top campaign officials. “There’s no way he’s going to come to an accommodation with her. He is not in this to compromise.

“The decision hasn’t been made when to make the announcement to go independent,” this source continued. “Right now, things are going great and he very well may upset Hillary in the New Hampshire primary.

“But as soon as she starts piling up delegates with the help of Wall Street money and her formidable ground operation, Bernie’s going to pull out and announce an independent run.

“Bernie’s polling has shown that he has a tidal wave of support among people across the country who have never or seldom voted. They’ll come out for him and pull the Independent Party lever.”

Such a prospect would be devastating to Clinton.
