the politics of security are largely about image (the politics of everything are), but the important thing to note is that you can't just whip up some issues and an "image" cooked to order when it comes time to run a presidential campaign. You need to have some idea of what it is you're trying to market, and some experience with various people actually trying to market it. And perhaps most important of all, one key element of "image" is not looking uncomfortable discussing these topics, and one easy way to do that is to actually be comfortable and confident that you know what you're talking about and understand where you want to take the country.
