@LouisIngenthron Political institutions shape the electorate as much as the electorate shapes political institutions. The electorate under an approval voting system would yield very different representation than plurality voting and primaries. The US Constitution is very self-consciously founded on the insight that "democracy" alone in not enough to form a decent state, careful institutions must organize and shape how the "will of the people" is formed and expressed.

@LouisIngenthron Where impeachment is not an adequate institution, we can make new ones. Why have laws against bribery, when there is always impeachment?
