They’re bailing rapidly from Roy Moore’s political campaign.

I refer to the Republicans in the U.S. Senate where Moore wants to serve. Bill Cassidy of Louisiana is the latest GOP senator to withdraw his political support for the embattled Alabama Republican nominee seeking to join the Senate.

Moore has this problem. A woman has accused him of making an improper sexual advance toward her when she was just 14 years old. That was in 1979 and Moore at the time was a 32-year-old district attorney.

There have been no criminal charges filed against the former state Supreme Court chief justice. Indeed, the statute of limitations prohibits a criminal complaint against Moore.

However, there’s this political element that has no statutory limit. That is where Moore is facing some seriously deep doo-doo.

No self-respecting Republican wants to serve with someone who must fend off these allegations. Never mind the Senate Democrats; they don’t want him in the Senate just because he is a Republican.

Sen. Cassidy’s decision to bail on Moore illustrates the huge — and still growing — problem the Alabama politician is facing.

Reason would dictate that Moore is going to lose the December special election contest against Democratic Alabama Attorney General Doug Jones. These are not reasonable times, though. I mean, after all, we elected a carnival barker as president of the United States a year ago.

Is it fair for a politician to be presumed guilty of doing something terribly stupid and likely illegal? Not if you balance it against how we treat criminal defendants.

However, we aren’t dealing with a criminal justice issue. In the rough-and-tumble world of hardball politics, Roy Moore is being forced to deal with a harsh reality.
