Why did I choose to characterize the Affordable Care Act as a cute widdle puppy dog instead of, say, a giraffe, a mole rat, or a giant squid?
Optics, baby. Pure optics. (Although on second thought that giant squid thing would have been SO COOOOL!) The important thing is that, like David Letterman's legendary giant doorknob, it's just big.
(For the record, I name everything "Morena Baccarin". Still a work in progress.)
