By way of preparing my own audience: It is possible none of this will ultimately matter. With numerous swing states polling within the margin of error, and the chance of a systemic poll error in play, Trump could very well win legitimately in November.
But if the election returns show that Harris has triumphed, Trump has a backup plan ready to go: He can attempt to subvert the election, as he did in 2020.
While elements of that plan could be different, the broad strokes of declaring victory, presenting himself as the victim of election fraud, filing pretextual lawsuits, and ultimately leaning on Republican officials at the local, state, and federal levels to hand him the presidency remain unchanged.
This strategy rests on Trump being able to convince the Republican base that he won the election. In 2020, he had the support of a vast right-wing media ecosystem that, with few exceptions, had already prepped its audience to disbelieve the results of the election if Trump won. The result was a violent assault on the U.S. Capitol that threatened American democracy.
Since then, the right has purged media figures and Republican politicians who had stood in the way of the plot. And now, in 2024, the same players are again laying the groundwork for a Trumpian subversion effort.
