Qualifications? You don't need qualifications to run a federal agency. You just need to be morally pure and never, ever have hired anyone to watch your kid or cut your grass without running a full background check on them.
Ask Bernie Kerik, who would have made a kick-ass head of homeland security. I only wish that the senate witchhunters would have some hindsight here and maybe we'll get qualified people in critical positions regardless of how many hookers they bang at a time or whether they did drugs in the '60s.
