You miss the point. There are democrats who will go to any length to protect their power. Condit got caught but he was willing to and did kill an intern to protect himself. The point is that in HOC they depict democrats who will go to any lengths for power and you can find in real life endless examples in the last couple of decades of democrats who have done anything and everything including murder to protect their power. That is the point and definitely not a stretch of the imagination.
What about alleged Republican Joe Scarboroughs aide who had the bad taste to mysteriously expire in his office in Florida and which the national press ignored after some misleading information was released by his office.
