Not Adventists. Very few in Iowa and not popular with Evangelicals.
Until Trump broadcast Carson’s faith I was unaware he belonged to a cult. This changes everything. Look it up.
I’ve known Seventh Day Adventists for years. I expect they might say your religion is a cult since it is different than theirs. Religions are what they are, religions. Some say the Mormon religion is a cult but we had a presidential candidate who was one. John Kennedy was a Catholic and many didn’t want a Catholic president. I remember the trouble that caused during that campaign.
