Louisiana Gov. Bobby Jindal questioned President Obama's intelligence today in a series of jabs that included an assessment that Obama has been a worse president than Jimmy Carter, who has has long been punchline for conservative Republicans.

Jindal's stinging remarks came before the Conservative Political Action Conference, a bastion of conservatives and a favorite spot for potential presidential candidates to audition their attack lines.

"We have long said this president is a smart man. It may be time to revisit that assumption," Jindal deadpanned. "Or at least to make a distinction between being book smart and truly wise."

That was just the opener.

"If I were him, I'd consider suing Harvard Law School to get his money back because I'm not sure what he learned in three years," Jindal continued, suggesting Obama might want to "actually read the Constitution every now and then."

(Obama graduated from Harvard Law School in 1991 and was the first African American president of the school's law review).

"How many moms and dads have told their little children that anyone can become president of the United States?" he said. "Unfortunately in 2012, we learned how true that is in this country."

Jindal even apologized to former President Carter, who he once called the most incompetent president in his lifetime.

"It's no longer fair to say he was the worst president," Jindal told the conference-goers. "Obama has proven me wrong."

The Louisiana governor, who is often mentioned as a potential 2016 presidential contender, also decried the president's "assault" on religious liberty, particularly the Affordable Care Act requirement that employers provide birth control.

"This president seems to believe that our religious rights, our First Amendment rights, start and end in the pews on Sunday," Jindal said. "I knew this administration doesn't like the Second Amendment to the Constitution - I thought they might still like the First."
