I guess Ann never heard of the Fugutive Slave Act or the Compromise of 1850 that strengthened that Act. Slaves were forcibly taken from free states back to slave states as a result of this Act. The Dred Scott decision involved a slave who was taken by his master to Illinois, a free state.
The forcible taking of slaves from free states to slave states as a result of the Fugitive Slave Act was one cause of the embitterment between the freedom-loving North and the slave-loving South.
If Ann is going to savagely attack Miers's legal credentials, then she should be prepared to face savage attacks as well. This sarcastic comment of hers that is flat-out wrong shows her to be ignorant of legal matters, and more of a shrieking head TV novelty act than a series legal commentator.
To call the North "Freedom Loving" as compared to the South is to twist the meaning of the word in a most Orwellian manner. Ask an Irishman, a Negro, an Indian, or a Catholic (of any nationality) how "Freedom Loving" the North was.
