"The bureaucracy IS sworn to serve the government of the day, but not at the cost of the public interest. The legislative side is accountable to the electorate to follow through on platforms and promises made, but also not at the cost of the public interest."
Problems arise when the two groups have different views of what constitutes the public interest. If bureaucrats, or any one else, wants to be the final arbiter of that question; they should pick up the nominating petion forms from their local elections office and start campaigning. Because as long as our governments want to claim to be democracies, only the people holding certificates of election get to determine what is or is not in the public interest.
