The National Rifle Association can crow all they want about protecting the rights of gun-owners, but what it's really about is selling guns. There's money in that, so the NRA, funded by gun manufacturers, can afford to lobby Washington to keep it easy for cash to flow in exchange for guns.

The people disenfranchised by voting registration, and moreso by proposed Voter ID laws, are not politically powerful, and by and large are a drain on the system. You can bet that the rich folk who want to pay less in taxes and want to cut the social safety net out from under the poor have NO problems registering to vote, and they want the people held up by that net to lose their right to vote so that senators and presidents can come in and gut entitlement programs.
