Maybe this a common thought, but I don't think I've ever heard it mentioned: Does anyone ever consider that part of the reason that Hollywood is so liberal in general is that it is one of the last remaining union strongholds? The film industry is unionized at all but the lowest levels (there's even a PA's union, but nobody joins it) and the unions ensure good wages, health care, and a variety of other benefits for a largely transitory (and easily exploited) workforce. Not that those unions don't have their problems (for both sides) but they aren't crippling the industry, in fact they keep it quite healthy. No wonder so many Hollywood types identify so heartily with the Democrats.
