Ronna McDaniel mess shows problem of politics-to-pundit conveyor belt

The former RNC chair was pushed out after a staff revolt - but why did NBC hire her in the first place?

It should have been a straightforward appointment in the often lucrative world of political punditry: a former high-ranking party official making the move from actual politics to America's television screens with a mission to pontificate, opine and spin.

US cable news is littered with such figures: ex-congresspeople, former presidential candidates, reformed spin doctors, one-time campaign leaders. All of them on fat contracts for sitting behind desks and arguing the political talking points of the day.
