How will this donnybrook finish?

Federal Judge Brett Kavanaugh insists he won’t withdraw his name from consideration to the U.S. Supreme Court.

Then again, that’s what they all say … until they do what they say they won’t do.

Donald Trump’s nominee to the high court is facing serious accusations that he sexually assaulted a woman in 1982; two other women have leveled similar charges. The FBI is looking once again at Kavanaugh’s background.

Three U.S. senators — all Republicans — stand at the center of this political tumult. Jeff Flake of Arizona, Lisa Murkowski of Alaska and Susan Collins of Maine are officially “undecided” on how they will vote on Kavanaugh’s confirmation. If two of them turn against Kavanaugh, it’s over, assuming that the Democratic Senate minority stands together in opposing Kavanaugh’s nomination.

If the FBI determines that Kavanaugh lied to the Senate Judiciary Committee about what he did back in the old days, well, that also is a deal breaker.

I cannot begin to predict it’ll happen, but I’ll just say I won’t be surprised if in the next 24 hours or so that Kavanaugh does what he says he will never do — and withdraws his name from consideration.

Hey, stranger things have happened.

Example? Donald Trump got elected president of the United States of America.
