Governor Romney has indeed said that he supported the original 1994 Assault Weapons Bill as recently as December 16, 2007:
MR. RUSSERT: Let me turn to gun control. Here's the headline: "Romney retreats on gun control. Romney, who once described himself as a supporter of strong gun laws, is distancing himself from that rhetoric now as he attempts to court the gun owners who make up a significant force in Republican primary politics. In his '94" Senate race, Romney backed two gun-control measures strongly opposed by the National Rife Association and other" guns rights "groups: the Brady Bill, which imposed a five-day waiting period on gun sales, and a ban on certain assault weapons. `That's not going to make me the hero of the NRA,' Romney told the Boston Herald.'" "At another campaign stop" "he told reporters, `I don't line up with the NRA.'" Suddenly Romney decides to run for president and signs up for a lifetime membership in the NRA.GOV. ROMNEY: You know, it's, it's wonderful, and you'll appreciate this. There is a great effort on the part of, in some cases, my opposition, in some cases, just folks that are interested in writing an interesting article to, to try and find any change at all. And my position on guns is the same position I've had for a long, long time. And, and that position is that I don't line up 100 percent with the NRA. I don't see eye to eye with the NRA on every issue. I...
MR. RUSSERT: You're still for the Brady Bill?
GOV. ROMNEY: I supported the assault weapon ban. I...
MR. RUSSERT: You're for it?
GOV. ROMNEY: I assigned--and I--let me, let me describe it.
MR. RUSSERT: But you're still for it.
GOV. ROMNEY: Let's describe what it is. I signed--I would have supported the original assault weapon ban. I signed an assault weapon ban in Massachusetts governor because it provided for a relaxation of licensing requirements for gun owners in Massachusetts, which was a big plus. And so both the pro-gun and the anti-gun lobby came together with a bill, and I signed that. And if there is determined to be, from time to time, a weapon of such lethality that it poses a grave risk to our law enforcement personnel, that's something I would consider signing. There's nothing of that nature that's being proposed today in Washington. But, but I would, I would look at weapons that pose extraordinary lethality...
MR. RUSSERT: So the assault ban that expired here because Congress didn't act on it, you would support?
GOV. ROMNEY: Just as the president said, he would have, he would have signed that bill if it came to his desk, and so would have I. And, and, and yet I also was pleased to have the support of the NRA when I ran for governor. I sought it, I seek it now. I'd love to have their support. I believe in the right of Americans to bear arms...
(‘Meet the Press’ transcript for Dec. 16, 2007, my emphasis added.)
I posted the full transcript last night. Everything he said about AWB was in the past “I supported”, “I would have supported”, “I would have signed”.
He was on record as supporting it at the time, and in 2002, and he was acknowledging that.
He also said in the portion you left out that he did NOT support bringing that AWB back, or ANY other AWB bill. He said he would not support any new AWB bills.
