Donald Trump still undecided to sign South Carolina's Republican Party pledge

South Carolina - The Republican billionaire presidential candidate, Donald Trump, on Thursday, said he would decide in time if he will sign a pledge for the Republican presidential nominee. South Carolina Republican Party requires signing the pledge in order to vie for SC's critical primary.

"Well, we have plenty of time to think about it because I think that's Sept. 30," Trump told during the campaign stop at Greenville, South Carolina. "There's a lot of time. So we'll be making announcements on different things over the next couple of weeks."

September 30 is the signing due date for Republicans to participate in SC's first ever presidential preference primary, USA Today reported.

He declared to New York Times he hasn't told anyone yet that he would sign the pledge.

The business mogul, who's the only Republican candidate to decline a third-party bid, says he anticipates a 10 to 15% increase on polls if he signs in.

During the campaign stop, Trump said, "The American dream is dead. But I'm going to make it bigger and better and stronger than ever before," the billionaire assures in his speech.

Tramp's remarks seemed to appeal on Republican polls as the Independent UK cited the business mogul got 35% vote on Monday Public Policy Polling.

Also, it appears that there's a demand for him to sign the pledge in South Carolina based on this week's poll, which mounts him 16 points ahead of Ben Carson, according to a news from The Guardian.

Just the day before, he presented his economic policy proposals with the catchphrase 'Make America Great Again'. He said he would simplify taxes.

He wants to change the tax code pointing it out to hedge fund managers who pay taxes lower than the regular income earners. He suggests eliminating inheritance/estate taxes for wealthy Americans as well.

In spite of his straightforward and frank remarks in the public, at this point, Donald Trump still appeals to the crowd discussing solutions to government issues that disrupt many Americans for years.
