"Does Rick Santorum hate freedom and happiness?"

Asks a WaPo blogger (Allen McDuffee), after reading what Cato Institute Executive Vice President David Boaz said:

[Santorum] criticizes the pursuit of happiness! He says, “This is the mantra of the left: I have a right to do what I want to do” and “We have a whole culture that is focused on immediate gratification and the pursuit of happiness ... and it is harming America.” And then he says that what the Founders meant by happiness was “to do the morally right thing.” He really doesn’t like the idea of America as a free society, where adults make their own decisions and sometimes make choices that Santorum disapproves.
