One of my takeaways from the long 2016 election season: both political parties put too much effort into electing a President who only has limited powers. The President is certainly an important symbol and they have a bully pulpit – and both parties in recent decades seem to be interested in increased executive powers, even if they want to exercise those powers in different areas – but they are only one part of the government. Voting for the right President is not a do or die affair: it is great for the media (and while they may not have liked Trump, they liked the attention he drew and the controversy around him) and perhaps more interesting to the public but I’m skeptical that a single good or bad leader can make all the difference.
I’d rather we view the American government as a complex system. Certain actors, like the President, may be more visible or powerful than others but they can rarely act unilaterally.
