Is it unreasonable to expect the press, especially respected members of the press like CBS News' Bob Schieffer, to hold guests to account when they make ridiculous, incendiary, defamatory statements about the President of the United States? Evidently it's only unreasonable when Democrats do it about Republicans, but it seems to be perfectly all right for RNC Chair Reince Priebus to liken the President to the captain of the cruise ship that sank in Italy last week. Here's what he said:

SCHIEFFER: But Donald Trump -- he's, kind of, worried about it. You heard what he just said. He said, you know, he thinks they're cannibalizing each other. Do you think that's going to all come out OK?

PRIEBUS: Now, the history shows, Bob, that -- that tough primaries and a little bit of drama are a good thing for the challenging party. Hillary Clinton and Barack Obama -- you know, they killed each other through June, and guess what? He won pretty easily. I think the evidence is there.

I think it's good for America. And in the end, in a few months, this is all going to be ancient history and we're going to talk about our own little Captain Schettino, which is President Obama, who is abandoning the ship here in the United States and is more interested in campaigning than doing his job as president.

SCHIEFFER: What -- what did you just say? What did you call President Obama?

PRIEBUS: I called him Captain Schettino, you know, the captain that fled the ship in Italy. That's our own president, who is fleeing the American people and not doing his job and running around the country and campaigning.

(LAUGHTER)

You made me think of it with all the ships behind you, Bob.

Really? See, if I were to consider a metaphor like captains of ships and the like, I'd think of Captain Chesley Sullenberger (Sully), who managed to save the crew and passengers of his plane by landing it in the Hudson River, saving all 155 people aboard the aircraft, instead of a cavalier, careless idiot like Captain Schettino, who had no business steering a ship so close to shallow water, failed to turn it in time, ran it into a rock and then leapt off the ship while passengers died in their life vests waiting to be evacuated.

Think about those metaphors. Who steered too close to the shore? George W. Bush and his merry band of regulators who sat around watching porn instead of paying attention to banks. Who failed to turn soon enough? Congress, perhaps, where Republicans routinely block each and every initiative to rescue this country from financial ruin? Who jumped into the life boats, leaving others to clean up and try and rescue as many as they could?

And yet, Bob Scheiffer's answer to Priebus?

SCHIEFFER: I -- I see what you're saying.

This is why we can't have nice things.
