In the end, these election disputes have confirmed the wisdom of the Founders’ decision to divide the power to regulate elections between the states and Congress. State involvement helps combat congressional self-dealing and undemocratic incumbent retrenchment, while congressional oversight helps curb state abuses, such as malapportionment and partisan vote suppression. And perhaps most important, by empowering Congress, not the president, to remedy deficient state electoral schemes, the Constitution prevents presidents from rewriting the election code by executive fiat and thus provides an additional safeguard against military dictatorship. Americans today should abide by its guidance.
