A few days from now, Liz Cheney will deliver the most consequential speech of her career to date. The polls indicate it will almost certainly be a concession speech.
Rhetorically, the assignment is clear: Accept defeat while sounding like a winner. More specifically, Cheney needs to signal that the loss of her Wyoming House seat in a GOP primary is in no way the end of her career, but the opening of a new phase.
She needs to invite the audience to imagine that they are not listening to a soon-to-be former congresswoman but instead to a possible future president.
