1 Well, frankly, I don't think there was a Chinaman's chance she would have been president (see what I did there?). I do wish Rep. Comer had said "Sit back DOWN, Mrs. Clinton, we aren't done yet!" But I don't think he had much hope of getting anything real out of her anyhow. They would need to have had her in chains (wonder if she would have enjoyed that?) to get her to hold still for any substantive questioning.

What hurt was watching Bill on the stand. I mean, it really did hurt! And again, I don't think they had much chance of getting anything substantive out of him. So what if he did play around with some of the girls on Epstein Island? Aren't they more concerned about security matters? Were they worried that Bill was gonna give state secrets while getting a massage? I'm sorry, but I thought most of that was unnecessary. 

2 Yes, they should have made Hillary stay there until they were done, even if it had no value. It's a matter of respect, and of showing they have the right to do so.
I doubt Hillary would like being in chains. She strikes me more as the type who would like her man in chains. In bygone days I would have said that wasn't Bill but then I saw that portrait of him wearing high heels and a dress...
Yes, the real danger was if Bill spilled secrets while there. That is, after all, the whole point of honey traps.
