Well, let me say first that there are some acts that transcend time. If Mitt had, say, been a male prostitute in his twenties, that would still follow him around. Just sayin'.
The other thing that disturbs me about this story is that it's so...
odd. Mitt driving around with dogs in the back of his pickup, not a great idea, but as has been said, lots of people do it. But NO ONE has said, yes, my family drove around with our dog on the roof, or our neighbors did it, or even, I've seen it a couple times on the highway.
I'd say what Vick did was far, far worse, but at the same time, I find it more understandable because he came from a background where dog fighting was commonplace (though Vick took it to an even more disturbing level). I have a hard time believing that a wealthy, educated man like Mitt simply didn't know any better.
I honestly don't know much about Mitt as a politician, but I'll admit I've seen some other stories that make me think that not only is he maybe indifferent to the suffering of others, but that there's something not quite right going on in his head.
