"I think after we get past the summer of silliness and insults, the voters are going to begin to look at who is prepared to do the job," he told Martha Raddatz on ABC's "This Week." "I believe I am the candidate best able to do this job on the first day."
Like several of his fellow Republican presidential candidates, Jindal said Trump has tapped into "anger" and "frustration" to draw his large crowds.
"What the polls tell me is that nobody really has any real voters right now," he said.
Several polls indicate Jindal will not be on the prime-time Republican debate stage next month. However, he remains confident he still has ample time to catch fire.
"We are seeing great momentum in Iowa. We are seeing standing only crowds, we are going to every county," said Jindal. "What I see is that voters haven't committed to any candidate yet ... this is a wide open race."
