Looks like they're trying pretty hard to smear Ron Paul. These kind of smear-attempts have been made during every single election campaign, even in the 1800s. In fact, IIRC, before Lincoln got elected, they tried smearing him, saying that he supported incest and rape.

I would not take this kind of stuff seriously... and I wouldn't take it seriously even for a candidate that I do not support.

But, it is their right (at least for now!) to smear him and whoever else they want as much as they please.
