Religion has no obligation to stay out of politics. It's the government that has a responsibility to stay out of religion. That said, of course people's beliefs affect their political views, so in that way without any direct effort at all the LDS church has an enormous amount of influence on the political decisions made in this state. The stake president took things a step further and from his official position in the church he advocated to his fellow church members specific political views. If the LDS church is cool with that then it is what it is. No wrong was done. But as far as I know the LDS church claims it stays out of these political issues, only advocating for certain moral issues that enter the political sphere. So, this issue is entirely within the LDS church. If they support those actions or not then that's their right.
