The Constitution’s separation of powers among Congress, the president, and the judiciary is a central element of the U.S. system of government, designed in part to enable each branch to prevent abuses of power by the others. When an abuse of power by an executive or a judge is sufficiently serious, the Constitution authorizes the legislative branch to impeach and remove the offending official. The Constitution’s authors — having just fought a revolution against a tyrannical king — especially feared the risk of abuse by a president; they consequently addressed impeachment in the Constitution even before outlining presidential powers. But the separation of powers is neither absolute nor explicit.
This essay focuses on the manifest weakness of the Constitution’s checks and balances in our current political environment, as demonstrated by the 2020 and 2021 impeachments of former President Donald Trump for abuse of power in dealings with a foreign nation and his attempts to subvert and nullify the 2020 presidential election. In light of Trump’s acquittals by the Senate, we face the question of whether impeachment works as a check on executive power and, indeed, whether checks and balances work overall. This question becomes especially salient if our election system is so flawed — or so hobbled by vote-suppression laws — that it cannot perform its primary constitutional roles of enabling a truly representative form of government and preventing tyranny. Unfortunately, we conclude that impeachment, without a working electoral system, cannot play its salutary role of protecting our democracy.
