Trump and Obama

GOP hopeful Donald Trump takes no insult without fighting back. Whether that insult comes from the president or the Pope himself, Trump doesn’t take disrespect laying down.

Earlier this week, President Barack Obama thought he’d be cool and slam Trump by saying he wasn’t a serious candidate. It didn’t go over very well.

“I continue to believe Mr. Trump will not be president, and the reason is because I have a lot of faith in the American people, and I think they recognize that being president is a serious job,” Obama said from the Oval Office on Tuesday.

Trump fired back at Obama with his own insult.

“You’re lucky I didn’t run last time when Romney ran because you would have been a one-term president,” Trump told the president in front of supporters in Beaufort, South Carolina.

Trump added that Obama has done a “lousy” job on spending, national defense, health care and immigration, according to The Hill.

“You look at our budgets, our spending, we can’t beat ISIS, Obamacare is terrible — we’re going to terminate it — absolutely terminate and replace it,” said the real estate mogul.

“You look at everything. Our borders are like Swiss cheese. This man has done such a horrible job, he’s set us back so far. For him to say that is actually a great compliment, if you want to know the truth,” he added.
