Here's the Tory Ad:

And here's where they found
their girl:
Wonder what she's looking at? It seems terrifyingly huge, and its frankly hard to imagine something like that belonging to a Conservative. (Except maybe to Stockwell Day who, I am told, is hung like a horse).
h/t to Jason, who never visits porn sites but apparently knows someone who does.
Update: Contrary to some of my commentors, there is no contradiction between being a girl in a stock photo and being a porn star. You might say our girl became a porn star the moment she appeared on the porn site. The definition of the term "porn star" is very loose. Girls have said to me, "Jesus, BCL, you're a regular porn star. I should be paying YOU."
I would never correct them.
