This sounds like an anti-Mormon question.
Religious bigotry is still alive in America.
Is it antisemitic to consider Andrew Fastow (Enron), Jack Abramoff, or Bernie Madoff horrible people? Or Arnold Rothstein (arranged the 1919 Black Sox scandal)? Lepke Buchalter, murderous gangster? Baruch Goldstein, who shot up a mosque?
No. Theft, fraud, political corruption, and murder are all contrary to Jewish teachings (and ideally in any religious heritage). People who do such things disgrace Judaism, arguably the most benign of all religions.
...If Mitt Romney has shown dishonesty in business dealings, has misrepresented himself as a politician, has had hypocritical involvement with the gambling and cancerweed industries, and has displayed cruelty to animals he is a hypocrite as a Mormon and a bad person.
