Well, yes, single issue politics has its risks.  I am glad to have found refuge in a secular democracy where both the head of government and the head of the opposition are not religious people.  One of the reasons that the US will do particularly badly (compared to the developed economies of Europe and Asia) during the decline of the oil age is the extreme religiosity and hostility to science in the US.  Many people are looking forward to another medieval period, which was the high point of church power.  And the US now has 5 co-religionists on the Supreme Court to make it so.
The anti-science stance of the Republicans may have more to do with the short term profits of corporations than their narrow branch of christianity. There are many christians who are realizing that war and neglect of the poor are not pro-life values. I've noticed the change in my own pastor.
