It wasn’t the GOA (Gun Owners of America), it was a STATE Gun Owners group. I think they were “GOAL” (maybe Gun Owners Action leauge) but I’m not sure of that.
The GOA link doesn’t denounce Romney, it says his various statements raise questions that have to be answered. The statement is undated, but in my opinion his press releases of December of this year answer their questions, as does this debate statement that he supports NO NEW GUN LAWS.
The “Gun Guys” claim to be pro-gun too... Doesn’t mean they are anything more than a Brady Campaign front group.
