Donald Trump was supposed to appear at a campaign rally in Wisconsin alongside Speaker Paul Ryan. As my colleague Jay Caruso reported, upon hearing Trump wax poetic about the best ways of sexually assaulting women, married and unmarried, he disinvited Trump from the rally, thus vindicating Erick Erickson’s decision at the RedState Gathering a year ago.

Trump was going to be replaced by his running mate, Mike Pence:

(hahahaha… debate prep…. hahaahahaha)

Now Mike Pence has cancelled his own appearance:

NEW: @NBCNews has learned Mike Pence is not going to the Wisconsin GOP event today.

and, no, Mike Pence was not disinvited:

MORE: Pence WAS NOT disinvited, but decided on his own not to go, per a senior Pence aide.

There really isn’t any explanation for this short of a full-blown mutiny underway in the Trump campaign. Major donors are pulling out of the race. Endorsing politicians are running like scalded dogs from Trump. Serious and substantial people are demanding that Trump pack his sh** and get off the battlefield. It seems like, based on the and on Pence’s condemnation earlier today, that Pence might be seriously considering walking away from the campaign unless Trump quits.
