If Christians had their act together, we wouldn't be talking about Obama's second term and we wouldn't have had Romney as a nominee. The reason the GOP has "a Christian problem" is because Christians have a Christian problem. Politically active evangelical Christians know more about the "gospel of conservatism" than they know about the Gospel of Jesus Christ. Christians need to get back to the basics.
"... the time will come when men will not put up with sound doctrine. Instead, they will gather around them teachers to say what their itching ears want to hear. They will turn from the truth and turn aside to myths. But you, keep your head, endure hardship, do the work of an evangelist, discharge the duties of your ministry."
