I don't know what you read but there has been quite a few articles by christians on the right who very clearly have criticized his past as well as present comments etc. but still believe overall his policies are more christian than what the Democrats offer
If you haven't read these articles it isn't a fault of the christian right - can I ask what websites do you read
I am from Australia and I have seen articles like this - maybe you are following leftist news so much you no longer have the ability to be impartial
