Sorry, a lot of people consider Rudy a "gun grabber".
Gun registration runs counter to the 2nd Amendment. It's not the government's business who has guns. It only becomes their business when a crime is committed.
Rudy backtracked some on his stance, and Hillary is much worse anyway.
I promise I am not trying to be difficult. Please explain to me how registration is infringing on the right to keep and bear arms.
