When scientists look at the bones of a dinosaur, why
do you think they decided the outside of a dinosaur
looks like a lizard rather than a furry animal or a
feathered animal?

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
