Nonsense. McCain is an unprincpled ass who has spent his political career deriding conservativism and supporting some of the worst causes of the left.
The conservative votes are there for him to earn. If McCain won't do that and he then loses the presidency to the Democrats it will be his fault.
If conservatives fail to defend America against the socialist party, they will help to deliver a mandate to President Obama. We all know who and what McCain is. And we know who and what the DEMs are. There's nothing to earn. The choice is clear. It's either McCain or Obama. You either help one or you help the other.
