He's not "a VP." He's the President.
Fair enough. So, I read the Newsmax.com interview with NRA president (not VP) David Keene. Although Keen doesn't state that his views are those of the NRA, the fact that he heads the gun owners organization and doesn't separate his comments from the NRA, implies that they do. This cannot be ignored. When a non-member of the NRA reads an interview with the new president of the organization and he rhapsodizes about Romney's attributes, that seems like a tacit, if not 'official' endorsement to me.
I don't wish to denigrate the NRA. However, if members like you disagree with what the president of your group is putting out there, you might want to make that known to him.
