Louisiana Gov. Bobby Jindal thinks the Republican party has come a long way since he made headlines in 2012 calling the GOP the “stupid party,” but Republican leaders still have to “earn the right” to lead the nation, he said over the weekend.

“I think the GOP needs to earn the right to be a governing party. We can’t just be the party of ‘no.’ We have to be a party of solutions,” Jindal said in an interview with George Stephanopoulos on ABC’s This Week.

Jindal, who has said he’s a couple of months away from announcing whether he will run for president in 2016, appeared on the Sunday morning program just a day after holding a mass prayer rally on LSU’s campus. The rally kept him from attending the Iowa Freedom Summit, a conservative event that drew at least nine other potential contenders for the GOP nomination and a lot of national media attention.

Early in the interview, Stephanopoulos asked Jindal whether it’s appropriate for a president to lead a spiritual revival and said he was struck by Jindal’s remark to the evangelical Christian crowd that “on the last page, our God wins.”

Later this week, Jindal is scheduled to speak to a group of Catholic business leaders in Florida.

“I think we are a diverse country. Obviously, a majority of our people are Christians, but we don’t discriminate against anybody, that’s one of the great things about America we believe in religious liberty,” Jindal said. “Thousands of people came together to worship and pray across racial lines, across political lines. I thought it was a great, great event.”

As court rulings continue to come down in favor of same-sex marriage across the country, Jindal said he would support efforts in Congress to pass a constitutional amendment that would allow states to continue to not recognize marriages between same-sex couples.

“I am proud that in Louisiana, we define marriage as between a man and a woman,” Jindal said. “If the Supreme Court were to throw out our law, our constitutional amendment — I hope they wouldn’t do that — if they were to do that, I certainly will support (U.S. Sen.) Ted Cruz and others that are talking about making a constitutional amendment to allow states to continue to define marriage.”
