Vote for the best candidate that shares your values.
It some cases there may not be much difference between the candidates.
I really don’t think you can judge by the religion label someone puts on. Nancy Pelosi is a Catholic. I have only good to say about the way active Catholics try to live their lives. Many people are Catholic but only on Easter and Christmas. When Pelosi says she knows more about abortion than the Pope she scares me and at the same time shows she is not qualified to hold any political office.
Harry Reid is a Mormon. I have only good things to say about the way active Mormons try to live their lives. Harry Reid is more than unqualified to hold a political office, I suspect he is unqualified to be a Mormon.
With Paul Ryan and Mitt Romney we have a Catholic and a Mormon who apparently try to live their respective religions. They both have found what they believe is the path to Christ and have decided to make that path an important part of their lives. They love The Lord and it shows.
To me what shows is much more important than the lable.
