What has McDowell ever done for Ireland?

CAN somebody please enlighten me as to what exactly it is that Justice Minister Michael McDowell is so convinced he has done for this country?

Maybe my memory is as faulty as that of his coalition partners at the tribunals, but since his intemperate, egotistical tirade, I have wracked my meagre brain for any trace of these monumental achievements of his that have transformed the Irish State.

All that comes up are that he and his PD party have kept Fianna Fáil in power unconditionally, despite several corruption allegations.
