Spicer fades into background, as Steve Bannon delivers the perfect parting gift: 'Sean got fatter'

CNN reports that whoever steps into the role after Spicer will have “very big shoes to fill.” Which is true. In the sense that the same can be said of any clown.

Spicer’s position as press secretary has seemingly been on the bubble since day one of the Trump regime, and for good reason. After weeks in which they simply ignored the press completely, Spicer burst out of the doors brimming with aggression and disdain for the media, ready to chide the Washington Post, fill the briefing room with Pepe’s finest, and turn this whole car around if people didn’t jump at his command. And then Trump—not the press—cut Spicer off at the ankles by saying something completely at odds with the official Word of the Day. Then he moved on to the knees. Then … higher.

The result has been that Spicer’s spent most of his time behind the podium (or in the bushes) in a petulant whine, half-cringing from media that points out that what he’s saying today is 180-degrees from what he said yesterday, half still engaging in a bluster that’s increasingly pitiful. No human being is so regularly trotted out to do an imitation of a whipped dog.

But the problem with communication at the Trump White House isn’t Sean Spicer. That’s not to say that Spicer brings any skill, credibility, or integrity to the role. He doesn’t. But then, neither could anyone else, so long as they were representing Donald Trump.

Spicer’s biggest problem is that he isn’t so much Trump’s press secretary as a Trumpologist. Like the Kremlinoligists of the Cold War era, Spicer appears to have essentially zero access to the subject of his semi-daily missives. Instead, he must cast bones in some antechamber of the James Brady Press Briefing Room, sniff the prevailing winds, and then sally forth to deliver his reports with some measure of ginned-up conviction. And he has to do so knowing that, at any moment, perhaps while he’s still trying to deliver these freshly-crafted talking points, Donald Trump is likely to scrawl all over them with … anything.

There seems to be far less evidence that Sean Spicer has any real connection to Donald Trump, than there is a reason for drawing lines between Trump and Vladimir Putin. If Spicer’s act were really a stage-play mounted by the boy-I-hope-there-is-a “deep state,” it would be no less disjoint from the actual motivations and actions taken by Trump.

And now, the end is near, it’s time to face … that we will miss him.

There has been plenty of speculation about Spicer's job almost since the first day of the Trump administration, when he came before members of the media to defend the new president's claims about crowd sizes at his inauguration. The chatter has ramped up in recent weeks, as he gave over many of his briefing duties to his deputy, Sarah Huckabee Sanders.
There will be other horrible press secretaries. Press secretaries willing to spit out Trump’s latest tweet as if it’s a haiku weighted by Deep Thoughts. Press secretaries willing to call on Fox, and Fox News, and a Fox affiliate represented by a laptop propped on a chair running Skype. Other press secretaries who flinch as soon as anyone starts a question with “Trump just tweeted ...” But none of them will manage the level of passive-aggressive, flop-sweat-soaked, barely-restrained mania that defines Sean Spicer.

Why is he leaving again?

I'm still having trouble understanding why Spicy doesn't just give 'em all the middle finger and get the hell out of there!"
