KEN MEHLMAN ON KARL ROVE

From a Frontline interview:

Give me a sense of [Karl] Rove. We all hear some myths, some realities. Give me a sense of the guy.

Karl is first and foremost loyal. That is the most important quality about him you need to know. He's loyal to the president in a way that very few people have ever been as an adviser to a president, loyal. Karl doesn't view his own agenda as separate apart from the president's, but his agenda is serving the president.
