Donald Trump Still Dismayed With RNC Despite South Carolina Primary Win

"I had no idea I was going to win by that much."

“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.

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."
