FFS sake. Mick's brought down Callinan and Shatter, revealed the sickening corruption in An Garda Siochána and NAMA, fought the vile vulture funds tooth and nail, battled against militarisation of Ireland and represented the poor and suffering at home and abroad with courage and conviction. That vastly overrides a little bit of a difficulty meeting tax bills. His work as a parliamentarian is priceless for Ireland Inc.
That said, I vote in Dublin Bay South myself.
