believe me you, it will be a huge issue. There is a reason that Romney (last week) bought a "lifetime" membership to the NRA. LOL. Romney and McCain have tacked right, even going so far as to renounce former liberal positions. Rudy has chosen to tapdance instead. Where that may work against Romney and McCain, since he can paint them as flip-floppers, it won't work against a guy who has been a rock ribbed conservative since he came into politics with Reagan in 1980.
I am 14 year member of the NRA - in good standing I might add.
I don't give a rats butt about Gun Control as a Presidential issue.
The second amendment is doing just fine - for law abiding citizens.
