If you took away the conservative Christian base then Republicans would not win anything, but what the Republicans do is be somewhat more conservative in order to get elected, and so end up doing the same things that Democrats do, except slower, thereby furthering the downfall of this country, which will not last in rejecting Biblical morality, and will share the blame for it.
You can support Stalin to defeat Hitler, but the victory you win will be short, so it is in voting for a compromised party.
the wicked shall do wickedly: and none of the wicked shall understand; but the wise shall understand.
(Daniel 12:10)
Our victory over Germany was "short"?
