And he nails it.

“He’s a nonserious carnival act,” Jindal said in a speech at the National Press Club. “Here’s the truth about Trump that we all know, but have been afraid to say. Donald Trump is shallow. Has no understanding of policy. He’s full of bluster but has no substance. He lacks the intellectual curiosity to even learn.”

Jindal, who has been stuck at the back of a 17-candidate primary field, called Trump a “narcissist and an egomaniac” who is “insecure and weak.”

“And that’s why he is constantly telling us how big and how rich and how great he is, and how insignificant everyone else is. We’ve all met people like Trump, and we know that only a very weak and small person needs to constantly tell us how strong and powerful he is,” Jindal said.

The correct response to Trump is to roll your eyes and pray that America is not yet stupid enough to elect him to anything.
