The quote about FOX news persuading conservatives that the Republican party is the party for them is risible on the surface. The author of the quote makes the classic mistake of assuming that FOX is wagging the tail rather than the other way around. As if Republicans would vote for Dems if not for FOX. That's such an outrageously idiotic assumption it invalidates the whole article with just that statement.
The more insidious assumption that is tact is that people do as they are told (by their superiors, clearly this must mean the affluent but intellectually lazy)
