Mormonism is a huge problem with Evangelical Christians.
They have an opinion about Mormonism that cannot be changed.
Many people do not know very much about Mormonism, but what they do know is not positive.
It is not a significant factor for me, personally, but I think it brings into question the electability of a Mormon, regardless of his abilitiues and qualifications.
OTOH, it doesn’t seem to hurt Harry Reid, and it didn’t hurt Mitt’s father, successful, longtime Michigan Governor, George Romney. But times were very different.
Not quite... They have a history of FACTS about Mormonism that cannot be changed; only spun.
