Agree with this, with a huge caveat.
From the perspective of JD Vance's rehabilitation of his image, it was a definite tactical victory.
But voters won't be voting for JD Vance on Nov 5th, they will be deciding between Trump and Harris.
I think Vance's performance was actually, big picture, a huge strategic loss for the Trump Vance ticket.
By putting on a performance that draws such a sharp contrast with his boss's demeanor, he spent two hours last night reminding undecided voters that there is another way and the chaos and drama are entirely unnecessary.
To the extent anyone saw it, the debate was a huge loss specifically for Trump.
