senators and congresspersons probably don't understand many of the bills they vote on, either.

do you really think most of those lawmakers suddenly decided that copyright infringement was a problem and banded together to create SOPA and PIPA on their own? organizations lobbied them to form an opinion. if nobody challenges those opinions, they just vote how the money tells them to.

if enough constituents tell them to change their opinion, they probably will. not because they really care personally, but because it will look favorable to the people that are in charge of reelecting them, and that will allow them to continue getting money from lobbyists over issues like SOPA and PIPA.

godaddy was in favor of SOPA for whatever reason, and only when they started losing money from it did they suddenly reverse their position and come out against it. lawmakers will do the same exact thing for the same exact reason if enough people call them about it.
