Keith timed his exit as both a Take That to the network brass and a boost to his now-former colleagues.He could've left a few months earlier, before the Lean Forward campaign; he could've left a week or so later, after the State of the Union. But he left after marketing spent a lot of money on new ads featuring him and the Friday before the biggest non-election event on the American political calendar, making a big splash and ensuring that many extra eyeballs would be on MSNBC. (Maybe not the Fox News crowd, but plenty of people who would normally have watched on CNN, C-SPAN, or one of the broadcast networks).
Keith was pushed out because MSNBC is owned by a big corporation that is willing to program liberal hosts as a market niche, but not economic populists (as that's bad for big corporations).Keith's being pushed out isn't guessing: It's fact. Some MSNBC apologists might see it as due to Keith's abrasiveness...but normally you put up with an abrasive employee to get ratings. When you look at MSNBC's record, though, it likes its hosts to be liberals that focus on social issues (e.g. environmentalism, civil liberties/rights) or foreign policy (Rachel Maddow in particular is foremost anti-war). Keith focused too much for MSNBC's brass on economic populism, including a stinging rebuke to President Obama when Obama extended all of Bush's tax cuts despite having a Democratic Congress at the time. Maddow agreed, but didn't focus on it. Lawrence O'Donnell actually supported Obama's decision. Also angered by Obama's relative fiscal conservatism was Cenk Uygur, who was sent packing despite getting much higher ratings in the 6 p.m. slot than Ed Schultz had, and Schultz had been promoted to prime time. They offered Uygur more money if he would quietly move to an obscure weekend slot. He refused. But then Schultz started getting aggressively into economic populism over proposed Social Security and Medicare cuts. He accepted getting moved to weekends, toned down his populism on those issues, and finally was let out of the penalty box back onto weekdays (though in a lesser slot). MSNBC hosts like Chris Hayes and Maddow can be to the left of Obama, but Hayes focuses on social issues (especially environmentalism) and Maddow on war and peace. Focus on economic populism and MSNBC won't let you keep doing it.
