McCain is a moderate on many issues. This is nothing new and has been discussed on Free Republic many times. That’s part of the reason he picked Mrs. Palin, because she is a conservative (especially on social issues) and will help bring out the conservative base for the ticket.
In terms of actual governing, the party platform doesn’t mean much, for either party. When McCain is elected, he will implement those policies he believes in (and that he can get passed), whether they are consistent with the party platform or not.
We've noticed that with the last several Repub Presidents.
The fact some nonchalantly overlook these flaws is what makes Conservatives angry.
