You maybe correct however for Romney he is lds right down the line. He is considered “temple worthy”, which means he is part of the 15% of lds (only 15% are onsidered worthy enough) who are allowed into the inner circle. He must follow all the rules. As a side note Harry Reid and Jon Huntsman are also “temple worthy”.
What about Glenn Beck?
My guess would be yes, I don’t know for sure. My experience is that people of means are more likely or it seems to be easier to be temple worthy.
