I'd argue that many of these "features" really ended up being poorly conceived in the long run and caused all kinds of unforeseeable side effects. In particular they completely failed to anticipate the explosion in urban population which has caused the voting power of those in urban areas to be greatly diminished. As a result of the electoral college and winner-take-all systems the interests of urban voters are generally grossly underrepresented at the federal level with respect to population size.

The founding fathers were smart, but nobody in the 18th century was smart enough to anticipate the requirements of a modern electoral system. Their real mistake though was making the electoral system both incredibly complicated and very hard to change.
