"Vice President JD Vance, a potential 2028 presidential contender, broke sharply with the president in owning the failures of the administration’s policies."

That's the WaPo subheadline, under the headline "Vance blames Republicans’ midterm losses on Iran war, cost of living" (gift link).

Here, read Vance's post. It doesn't strike me as a "sharp break" from Trump. I see it as just analyzing the  substance of yesterday's big losses:

"I wasn’t on the Ballot and if I was, we would have won IN A LANDSLIDE! Thank you for your attention to this matter. President DONALD J. TRUMP."

Wrote Trump, on Truth Social, 7 hours ago.

6 hours ago, he wrote: "I’m going to become a Political Pundit, both good and bad, on the reasons these Candidates won and lost! President DONALD J. TRUMP."

It's pretty obvious how this punditry will go. 3 minutes before that post, he'd opined on Greg Abbott: "If Greg Abbott, the Governor of Texas, hadn’t become a RINO in the last six months of his Political Life, he wouldn’t have lost. He went back to his original formula, and it wasn’t pretty! President DONALD J. TRUMP."
