Donald Trump said the Republican Party missed the mark with Mitt Romney as its presidential candidate in 2012, and better get it right in 2016 in order to beat probable Democratic opponent Hillary Clinton.
Trump, in an interview with ABC's "This Week" reporter Jonathan Karl at the Iowa State Fair, said if he ran for president he said he would "spend whatever it took" to win, revealing his net worth at $10 billion.
"Mitt Romney… everything should have been good, but it didn't work," Trump said. "He didn’t resonate. They have to pick the right candidate."
The interview came the day after Trump addressed Iowa Republicans, where he said that Clinton, the former secretary of the state, would be tougher to beat in 2016 than Obama last year.
"Hillary is going to be tougher to beat" than Obama's 2012 reelection campaign, Trump said, and he urged Republicans to choose "the right person, the perfect person" at their next convention, ABC News reported.
The billionaire real estate mogul touted his financial wizardry as a key reason Americans should take him seriously if makes a run for the presidency, NBC News reported.
"I've built a tremendous company -- I've built a net worth that is a fantastic net worth," Trump said during a speech to conservative Christians at the Family Leadership Summit in Ames, Iowa.
"I have very little debt, I have tremendous cash. We have to create tremendous wealth so we can take care of Social Security and Medicare and all of the things that we can't afford right now. And I think I'd be very, very, good at doing that," Trump said.
Trump considered a run against Obama during the 2012 race but ultimately resisted entering the crowded GOP primary field. However, his appearance in Iowa signals he is seriously exploring whether to enter the next race.
Trump also discussed the growing negative perception of the U.S. abroad.
"We used to be the king and the queen all put together, and now we're a laughingstock as a country," Trump said.
As for divisions within the House Republican caucus, Trump recently said party infighting would be destructive for the party.
"There is a problem, and part of the problem for the Republicans is you have two very divergent groups," Trump said. "You have people that are hard-liners that want very much to see [the government] shut down; you have others that are not so hardline but they want Obamacare ended because they know how destructive it'll be."
"And actually, the Republicans are going to have to get together and choose one or the other," Trump said.
In the interview with Karl, the ABC reporter asked Trump about his pursuit of Obama's birth certificate, suggesting it made him look not serious.
"Why does that make me not serious? I think that resonated with a lot of people," Trump said.
Trump said "I have no idea," if Obama was born in the United States.
"I don’t know, was there a birth certificate? You tell me. You know, some people say that was not his birth certificate. I'm saying I don't know. Nobody knows. And you don't know either," Trump said.
