I am a conservative and would have supported the law because I honestly don't care if your right to sell a high capacity rifle to a convicted felon is infringed but it isn't a voting issue for me. Start to infringe on my right to own and protect my family and that changes. For you I would assume it is a voting issue. If Obama wanted to increase me level of involvemtn he should have spent more time showing me how it would make a differience and less time trying less try to work up his base.
The politician can safely ignore my view on this issue since ti is way down on my list but he can't ignore yours even if more people agree with me than with you.
