(CNN) Louisiana Gov. Bobby Jindal won't join the ranks of politicians who have "so called evolved" on same-sex marriage, he said Tuesday.

Jindal, a Republican who is considering a presidential run, suggested that politicians like President Barack Obama and former Secretary of State Hillary Clinton changed their views on gay marriage because of polling indicating more Americans in support of gay marriage.

"I'm not one of those politicians," Jindal said on CNN's "New Day." "My faith teaches me that marriage is between a man and a woman. I don't believe in discrimination against anybody. I'm not for changing the definition of marriage."

A CNN/ORC poll in December found that 57% of Americans support gay couples' right to marry, including 36% of Republicans.

Jindal may be in the minority on the issue when it comes to the issue, but that won't be the case if he joins a crowded Republican primary expected to be full of same-sex opponents, like former Arkansas Gov. Mike Huckabee.
