Former Governor Mike Huckabee has made disparaging remarks about atheists in the past. Justin Scott, an AtheistVoter from Iowa, asked Huckabee about his commitment to the separation of church and state and why an atheist should vote for him, given some of the things he's said about atheists. 

In his answer, Huckabee says he's never disparaged atheists (he has, here and here) and repeats some lies about the "persecution" of Christianity.
