I think the problem is that the "old" people just don't understand the bills. Call it Counter-terrorism, or anti-child-porn and you've got people signing because having a " nay" on a loosely languaged bill probably means fodder for attack ads down the road.

"Congressman [x] voted NO on stopping cyber terrorism"

My rep pulled support for SOPA at the last possible second, and only after public out cry. I sent him a letter thanking him for actually listening to his constituents, but kindly asked for him to resign. If these people don't understand the technology they're being asked to regulate, they should be replaced by those who do.
