As Donald Trump and Hillary Clinton firm up as the nominees in next year's US presidential election a third-party candidate by the name of Deez Nuts has surprised the nation by polling favourably among a significant portion of Iowa voters.

Borrowing his moniker from an internet meme, "Deez Nuts" is in fact a 15-year-old Iowa boy named Brady Olson who registered to run for president with the Federal Election Commission on July 26, The Daily Beast reports .

And despite his tender age, Deez is making an impact in the polls. He is currently polling at 9 percent and would theoretically take almost one-in-10 votes in a three-horse battle with Clinton and Trump.

Brady said he is essentially running for president because he can.

"When I heard about the Limberbutt McCubbins story, I realised I could," the teen said, referring to a cat from Kentucky that is seeking the Democratic nomination for president.

"The next step is to get some party nominations, like the Minnesota Independence Party or the Modern Whig Party," Brady said.

"It would also be great to find a VP, preferably McCubbins because the Nuts/McCubbins ticket sounds amazing."

Deez Nuts came to public attention after Brady approached Public Policy Polling and informed them that he was running for president.

"He said, 'I'm Deez Nuts. I'm running. Here's my filing statement. Would you poll me?'", polling specialist Jim Williams of Public Policy Polling said.

Mr Williams thought 'why not' and pitted Deez Nuts against Clinton and Trump in Minnesota a few weeks ago.

To his surprise the third party candidate polled at 7 percent and his star has been on the rise since then.

Brady said his candidacy is both a joke and a political statement.

"I saw the slop bucket that we call the GOP field, the one-woman show on the Democratic side, and the lack of any third party candidate and thought 'Man, Deez Nuts would be better than any of these guys'. So after that I just ran with it," he said.
