Donald Trump: 'I have a Gucci store that's worth more than Romney'

Donald Trump doesn't think Mitt Romney can compete with his business success.

In an interview with the The Des Moines Register published Monday, the real estate mogul and television personality dissed other wealthy men who have campaigned for president.

"I'm the most successful person ever to run for the presidency, by far. Nobody's ever been more successful than me. I'm the most successful person ever to run. Ross Perot isn't successful like me. Romney - I have a Gucci store that's worth more than Romney," Trump said.

Mitt Romney ran for president in 2008 and was the GOP nominee in 2012. Ross Perot mounted two third-party campaigns in 1992 and 1996. Like Romney and Perot, who poured millions into their own races, Trump has indicated he would be willing to self-fund his 2016 presidential campaign if he runs.

In addition to his comments about Romney, Trump also had a creative answer when The Register asked him about the Islamic State jihadists (also known as ISIS) in the Middle East.

"I have an absolute way of defeating ISIS, and it would be decisive and quick and it would be very beautiful. Very surgical," Trump said.

However, Trump, who has accused other Republican White House contenders of stealing his campaign slogan, wouldn't elaborate on his plans to prevent them from being taken by other candidates.

"If I tell you right now, everyone else is going to say: 'Wow, what a great idea," he said. "You're going to have 10 candidates going to use it and they're going to forget where it came from. Which is me."
