One joke among pundits in Washington D.C. is that the job of communications director for President Donald Trump is cursed.

It isn't cursed. It is just impossible.

Some look at the list of communications directors over the past 50 years and note that President Trump has sent more directors to their next job in two years than any other President in four or eight years.

Perhaps it is the turmoil. Maybe it's the scandals. It could be the horrible relationship this administration has with the press.

I'm sure all of those things make the job difficult. But the real issue with the job is that you are never the one doing it.

The White House Communications Director in the current administration has been Sean Spicer, Mike Dubke, Anthony Scaramucci (for a glorious two weeks), Hope Hicks (after she finished steaming Trump's pants while he was wearing them), and former FOX News President Bill Shine (who left the channel after multiple sexual harassment lawsuits).

Now Shine has resigned to move from his current post the 2020 re-election campaign.

There is a lot of excitement over who the new communications director will be. The communications director will be the same one that has been in place since the November 2016 election - Donald J. Trump.

Between his off-script speeches, off-topic press conferences, and his omnipresent Twitter feed, President Trump has never displayed the ability to "stay on message" when it comes to the goals of the administration.

A big part of the communications director's job is to frame the administration's goals and activities to shine a positive light on the work and help gain or maintain support.

Trump doesn't do that. The only message he has stayed with is the "no collusion" line. He can do it. He picks nicknames for Lyin' Ted Cruz and Little Marco Rubio and others and can keep that narrative strong.

But even when it comes to his own pet project - the wall across the country's southern border - Trump has shown no discipline at all. He has declared the situation at the southern border to be a national emergency. Then he told reporters that he could have waited for Congress to fund the wall but the emergency declaration was simply faster. Of course, that sentence will be used in every lawsuit against the wall, and probably successfully. Trump also can't keep from calling it a wall when others have deemed that steel slats or a fence are terms that more people are willing to accept.

He will change the terminology briefly but then revert to calling it a wall again during an interview or a Twitter tirade.

Guess who has to reconfigure all messaging after that spur of the moment decision by the President? Guess why Trump is about to hire his sixth person for that job.

Some people love what Trump is doing in the first half of his term. Others hate it. One thing is certain, nothing is normal, predictable or even controllable. I can't imagine taking that job. I know there are some who believe they have the secret recipe to make it work. Five of them have already seen their secret recipe fall apart when the heat was turned up. It should be interesting to see who is chosen and what changes are made in that department and whether the new director will still be around to see the July 4 celebration.
