Conservatives need to know how important it is to fill out the census. It is one of the only things our Constitution specifically asks of U.S. citizens and boycotting will just help liberals expand government even further.
I think we need to start with Philadelphia and make sure that we actually get some election reform in Philadelphia. Actually, a recent election was thrown out by a federal judge because of corruption with the voting process in Philadelphia.
It's often difficult for conservatives to separate overall government intervention from a question as simple as the census.
