We told you MSNBC chief Phil Griffin has made David Gregory his trophy boy. That’s why the 6pm anchor was lavished with airtime during yesterday’s North Carolina and Indiana primary coverage. Which meant morning boy Joe Scarborough, accustomed to ankling this type of coverage with Keith Olbermann and Chris Matthews, grew furious when Gregory hogged the cameras — so much so, Jossip hears, that he stormed off the set and never returned for the rest of the evening’s coverage.

Sound familiar? It should. Last month, Scarborough pulled the same stunt while guesting on Gregory’s Race to the White House after growing furious with Rachael Maddow.
