How does the GOP plan to enforce its platform position on pornography?

So we really have three possible outcomes:

The crackdown on porn is doomed to be utterly ineffective at preventing the supposedly harmful effects of porn on its viewers, and on the viewers’ neighbors.

The crackdown on porn will be made effective — by implementing a comprehensive government-mandated filtering system run by some administrative agency that constantly monitors the Net and requires private service providers to block any sites that the agency says are obscene.

The crackdown on porn will turn into a full-fledged War on Smut that will be made effective by prosecuting, imprisoning, and seizing the assets of porn buyers.
