Let’s clear this up: Voters, through the electoral college, decide who wins the presidency. If the legitimacy of the vote is in question, the next appropriate course of action is the legal system, the courts. No one is delegitimizing the voters by pursuing legal action.
EVERY citizen and EVERY politician should demand to verify the integrity of an election in question. Otherwise, we will never recover.
Whomever wins, wins. But we owe it to future generations to find the answer to the question of which man has legitimately won the election.
