I must have missed the part of W's platform where he calls for censorship of video games. Perhaps you'd be happier with a party that believes it takes a village to raise a child.
W was reelected because America is in the midst of a full bore Christian revival that sees no reason why America popular culture cannot be what it was before 1970. It happens historically. A full bore Christian revival replaced Regency culture with Victorian culture. And it was Christianity in the first place that displaced the carnal culture of late antiquity.
We have already seen the cultural reaction building up and it is only starting as America gets redder and redder. And it is what makes defenses of GTA on "free speech" ground so ridiculous. GTA was never meant for adults. It was always marketed entirely to children. It was never meant for "mature" audiences. It is a shot across the bow from mass media to every family in this country. The people who created GTA have targetted your child. So censorship is how parents fight back.
