I haven't used the NRA's rating in a decade. They care more for "hunting" than for actual Second Amendment Rights.
Governor Mitt Romney and Firearms Policy According to his 2002 gubernatorial campaign, Romney “is a supporter of the federal assault weapons ban. Mitt also believes in the rights of those who hunt to responsibly own and use firearms.” July 1st, 2002 Mitt Romney signed a permanent ban on Assault Weapons. “Deadly assault weapons have no place in Massachusetts,” Romney said, at a bill signing ceremony with legislators, sportsmen’s groups and gun safety advocates. “These guns are not made for recreation or self-defense. They are instruments of destruction with the sole purpose of hunting down and killing people.”
Whoops... So much for Mitt having a clue about what the Second Amendment is for.
Whoa...talk about myopic.
If you do your research and look talk to anyone from the NRA you will see that in Mass, if Mitt had vetoed the assault weapons ban bill it would have been overturned and became law as the Dems wanted.
So he worked with the NRA and the Dems in the legislature to get the worst parts out of the bill. So yes he signed the bill, but it could have been much worse had he not worked with the NRA to craft it.
FWIW Romney actually took steps to protect the rights of gun owners as governor:
In 2006, Romney signed NRA-backed legislation creating exemptions for the makers of customized target pistols who had found it too expensive to sell their guns in Massachusetts because of a state regulation requiring them to test at least five examples of new products "until destruction."
