That's mostly true, except MA's gun laws aren't 'draconian,' they just are worse than most states, and Mitt did what he could to make them less draconian. And I think he doesn't want to spend anymore time at a Harvard Alumni event than at a VFW - he'd much rather just be with his wife or family doing a Mormon Family Home Evening and eating jello.
Given his record and those whom he has advising him on the issue, he will likely be the most 'plugged in' president on the 2nd amendment ever elected.
Besides, if he ever did articulate that he understsood the 2nd amendment as "The violent, killing opposition to government", his campaign would be over.
If you aren't aiming for
Gold Star Carry status, you aren't our friend no matter what other platitudes you mouth. Same goes for support of ugly weapons bans, midnight special bans, and "gun show loophole" canards.
Yes, this issue is just that important.
