"I’ve already done one, I’ll do plenty more," Mace tells the man. "You’re always invited."

"It’s a simple question," the man responds.

The conversation then turns when Mace informs the man that she "voted for gay marriage twice," a point that seemingly offended the voter.

"You’re insane," the man responds. "You’re going to be voted out so fast this year."

Afterwards, Mace posted the exchange to social media.

"I hold the line 24 hours a day, 7 days a week, 365 days a year. Try me," she said in the post.

Mace’s office did not immediately respond to a Fox News Digital request for comment.
