You have to really worry about a man who can’t see a scam, even after it has been pointed out to him.
Who says he doesn't know global warming is a scam? He might be in on it with the other con artists who are trying to destroy our economy and tax us into oblivion. A destitute hopeless electorate is good for socialists because they are good at promising to care for us if we just allow them to control our lives.
Once they control every aspect of our lives, they couldn't care less if we starve to death because it isn't prosperity that socialists seek. It is power.
PS. McCain is a socialist, in case that wasn't clear.
