Thesis: The executive branch is becoming too powerful.
Antithesis: If that ever happened, the white-collar desk jockeys at the IRS would rise in revolt against authoritarianism.
Synthesis: Democracies cannot be authoritarian as long as they pass the 
test.
Seeing the way liberals talk about places they do consider to be dictatorships, be it Russia, DPRK, China, you'll realize the answer is emphatically yes.
