milking a bull brings to mind a very funny story I have of several of us country folk having some fun and we convinced a young New York City gal, fresh into the country that she had to at least experience that. In her case, it was milking a billie goat. He loved it of course. Everybody held their laughter and encouraged her and even after she "got the milk" she didn't know what she'd done other than to say "that doesn't look like milk"

But your bringing it up makes no sense to me in context because the truth is that Obama and McCain are one in the same and you still can't see the that there is no difference in what it means for any of us in the long run. You will just always side with the left (Hello Nancy Pelosi) no matter how bad they (you) look. And that's a sad story in and of itself.
