Despite his reputation as a humorless plank of wood, I actually enjoyed this interview quite a bit. I guess no longer running for president but still having your party control the White House and the Senate loosens a guy up. Although he makes too many half-joking references to his failed candidacy for me not to think that still stings a little bit.
Also, my former roommate pointed this part out:
Q: Think of one of your least favorite people in Washington and, without naming names, describe what makes that person so unappealing.
A: Disloyalty is the trait that burns me up.
That sounds an awful lot like a dig at you-know-who.
