if a category that includes teachers , who undoubtedly numerically overwhelm everybody else in the category, is only 51% Obama, then it tells you the category is lumped to obfuscate; you would have no idea from this whether doctors, engineers, etc. as individual occupations support Obama or not. The intent seems to be, “see all the smart, educated people are for Obama.”
You raise an excellent point and I’m inclined to agree that what you are suggesting is exactly what was done to manipulate the statistics.
Holy cow! You nailed it. Teachers are lumped in with doctors, architects, engineers, etc? Why don’t they lump journalists and womyn’s studies professionals in that category, too?
