>Ok, let's make this more generic. How many republican senators find no fault with the wiretaps, incommunicado incarcerations, reading of citizens' mail, etc but feel that gun registration is an invasion of privacy. My bet (with no numbers to back this up) is probably only a very few short of 'all'.

Honestly, lose the (R) moniker there. There are plenty of (D) representatives who like nothing more than spy on their citizens. Once again think Japanese Internment, FBI spying on MLK Jr., Echelon... not to mention the current incarnations which have been overseen by committees with members of both parties. There is no left/right distinction in practice, there is only government/citizens.
