Successful people always have a Plan B if their first plan fails.

If Donald Trump ends up losing the presidential election to Hillary Clinton, the brash billionaire’s Plan B may just involve launching his own multimedia conglomerate.

With 14 million people having voted for him in the Republican primary, the former star of “The Apprentice” already has a passionate fan base ready to devour his populist message.

And if the polls hold true, Trump will lose in a landslide and look to re-invent himself. It’s no secret the Trump brand has been damaged during his run for the Oval Office — his perceived racist rhetoric has led big-name sponsors like Macy’s and ESPN to end their lucrative business dealings with “The Donald.”

But as the campaign has progressed, the Republican nominee has surrounded himself with people with media backgrounds.

Which means Trump has the people in place to build a powerful voice and appeal to his ardent supporters.

The Trump campaign’s second staff shake-up in as many months saw the resignation of former chairman Paul Manafort and the addition of Stephen Bannon as campaign executive.

Bannon, who has never worked on a political campaign, was the chief executive officer of the conservative news website Breitbart. Bannon is a political flamethrower who would be the perfect person to run a future Trump digital outlet.

Bannon also has a background in television and documentary filmmaking. Trump Films has a nice ring to it.

Trump also added recently ousted Fox News Chairman Roger Ailes to his team as he prepares for three general election debates. Ailes, who was the most powerful person in American media for the last two decades, built the highest-rated cable news channel. A longtime friend of Trump’s, Ailes could certainly create a Trump Cable Network.

I could even see Sean Hannity and Bill O’Reilly abandoning Fox for total control of their new cable shows.

If this political thing doesn’t work out, building a multifaceted media platform would be a great way for the casino and real estate magnate to rebuild his brand and continue to be the center of attention — something he craves.

If it works out, I bet Trump would be able to surpass his friend Howard Stern as the “King of All Media.”
