Actually, a person who never changes their mind is a danger.<quoted text> Isn't he the same guy who was against same sex marriage until he realize he needed to support it to get re-elected. A president who changes opinions with the political winds is a danger to the republic.
Presiden Obama thought that a civil union approach was a solution. When it did not, he changed his mind for the legalization of same sex marriage.
As for the election, a person in favor of sane sex marriage would still consider Obama a better option that Romney - who had a proven dislike for gays as shown in his prep school assault.
