Joe Wurzelbacher, the Person of the Third Debate

So, there was Joe the plumber, Sen. John McCain's friend, who would become famous for complaining that he shouldn't face an extra tax burden for making a yearly net profit in excess of $ 250,000.

McCain, who, however, failed to give a concise picture; when he wants the federal government to guarantee home-owners' mortgages, where is he going to find all the money to do so?
