Caitlyn Jenner on Wednesday was asked why she wasn't a Democrat.

The 66-year-old Jenner spoke for an hour at a sold-out event at the University of Pennsylvania.

Jenner was interviewed on the stage of the university's Irvine Auditorium by Buzz Bissinger, who wrote Jenner's coming out story for Vanity Fair.

When a student asked Jenner why she wasn't an ardent Democrat, the I Am Cait star replied: “I have gotten more flak for being a conservative Republican than I have for being trans.”

“Just because you change gender doesn't mean you change your core beliefs,” Bissinger interjected.

Elsewhere in the talk, an emotional Jenner said that she regretted not coming out to her father William Jenner, who died 15 years ago.

“That will always haunt me,” she said. “I think eventually he would have come around. He would have never understood, he didn't know anything – gay, trans, all that other stuff. But I'm sure he's looking down from heaven right now and saying, 'Well, you're doing a good job. You're making a difference.'”
