Santorum compares abortion to slavery in new book

Another look at Senator Santorum's new book, It Takes a Family: Conservatism and the Common Good, from CNN: Inside Politics.

In the book, Santorum makes the case that abortion puts the liberty rights of the mother before those of her child, just as the rights of slave owners were put before those of slaves.

"This was tried once before in America," Santorum writes. "But unlike abortion today, in most states even the slaveholder did not have the unlimited right to kill his slave."
