Yes, but is complicated.
I'm colombian. Here, the green candidate for president, Antanas Mockus, once said in an interview that he didn't believe in God. I don't have a problem with that, however, the week after, as he saw he was losing votes with that statement, he said that he does believe in God, his family, and even the Catholic Church started defending the candidate.
I think you can't change your faith in two days. I would vote for an atheist candidate if he or she is convinced that God doesn't exist. I would vote for a christian candidate if he or she really act in government like a christian would act (Solidarity, tolerance and other values).
