The slow-motion train wreck of the Republican presidential campaign is now beginning to accelerate as the Trumpenstein takes control of the locomotive.

Fox News executive vice president Michael Clemente confirmed the cancellation in a statement, saying after Ohio Gov. John Kasich said he wouldn’t attend the event without Trump, “there needs to be more than one participant.”

“Ted Cruz has expressed a willingness to debate Trump or Kasich – or both,” Clemente said in a statement provided to TPM. “But obviously, there needs to be more than one participant. So the Salt Lake City debate is cancelled.”

Yes, obviously.
