Exactly what I have been saying (but not as concisely), Obama/Romney are just a symptom of the problem. The real problem is the voters. The so called Christian voters who no longer believe or only partially believe, or only believe when faced with their own mortality.
Bottom line, the voters will answer the surveys one way and vote ( and live) another.
All of the profusion of competing Christian groups and sub groups have diluted and confused the message. You can shop for a church that believes anything from black liberation to white supremacy to drinking Koolaid in the jungle.
The legitimate Christian leaders need to get together and address this problem. They have sheep wandering everywhere.
