An analogy: Like many people who were fans of his in the late 1970's, I refused to believe O.J. Simpson was guilty...until he got in his Bronco and went on the lam. Only a guilty man does that. Only a guilty person does everything possible to avoid testifying in court.
The most suprising thing - wait, the ONLY suprising thing here - is that Democrats are actually saying they are going to show some backbone and issue subpoenas tomorrow.
It's a whole new world.
