Donald Trump Still Dismayed With RNC Despite South Carolina Primary Win

— -- GOP front-runner Donald Trump again said he was being treated unfairly by the Republican National Committee despite his overwhelming win in the party's primary in South Carolina Saturday.

“I don’t think I’m being treated fairly by the RNC,” Trump said Sunday on "This Week" following his double-digit win in South Carolina over Florida Sen. Marco Rubio and Texas Sen. Ted Cruz.

“I had no idea I was going to win by that much,” he added. Trump finished with 33.5 percent of the vote in his second primary win.

But the billionaire businessman, who has expressed his dismay with the RNC before, maintained he didn't plan to run as an independent if he lost the Republican nomination, saying, I don’t think that’s much of a possibility” when asked.

Despite his front-runner status, Trump said being an outsider within the Republican Party has left him disadvantaged, especially during debates.

“I walk in and they all have special interest lobbyist and donors sitting in the room and I don’t have any donors because I don’t have any special interests and I don’t have any lobbyists,” Trump told ABC’s George Stephanopoulos. “I walk in and it's dead silence except for my wife and kids, and these guys walk in and they say something that is stupid and not even good, and they get standing ovations when they open their mouths. It’s very unfair in terms of the debates.”

The real estate mogul added he was also hit hard with negative ads in South Carolina by Cruz’s campaign.

“I said to myself, wow, this is a tough business,” Trump said. "These people are worse than Manhattan real estate developers."
