But this ad's going to appeal to who he wants it to appeal to: the conservative Christian family who doesn't really bother to understand these issues, but is frightened of them anyway.
CUZ THOSE RELIGIOUS R BIG DUMMIES!
Not what I meant. Pretty much every voting bloc has some issues where most voters feel strongly and vaguely. Conservative Christian voters probably mostly support limitations on pornography to some extent. I'm sure it tested well among Romney's focus group members. But few bother to understand the mechanics behind any such governmentally-enforced prevention. If they did, they'd probably realize that this is a pretty empty promise on Romney's part.
I'm not blaming the voters for being undereducated (it's a complex, technical issue) or falling for pandering. I'm not even blaming Romney for using a pipe dream issue. It's just the nature of politics.
There's no voting bloc that is especially educated on this issue (maybe Ron Paul supporters)...it just happens to be that this voting bloc is the one that's most interested anyway.
