Nope. I merely stated that it was the point of the author. If she is wrong, OK. But there’s nothing in the Constitution prescribing the “winner take all” approach, either. It says the states can decide how they select them, correct?
To be more precise, it gives the power to state LEGISLATURES to select electors in any manner they choose, so it’s just as accurate to say that there is no right for citizens to VOTE for president in the US Constitution, as that resulted from a delegation of that power from the states (starting in 1824), which can be withdrawn at any time through amendments to any or all of the STATE constitutions that adapted that method.
And even under those state constitutions, citizens STILL don’t have the power to vote FOR president, since the state only has the power to delegate its right to chose its electors for president ... so it’s just as accurate to say that a NATIONAL popular vote for president is a FICTION, since no such popular vote actually exists ... as no citizen is really voting FOR a president on election day.
