Nowhere left to turn - Martin says no coalition with Fine Gael or Sinn Fein

WITH that one phrase and in one fell swoop Micheál Martin has brought ideology back into Irish politics.
Fine Gael is too right-wing for Fianna Fáil and Sinn Féin is clearly too left-wing for them. We can only surmise that Fianna Fáil is in the centre but what exactly is that in the post-troika Ireland of 2014?
