Yes, if the figures in the media over the last few days are correct, the entire dail should probably be called on to resign for this 'offence'.
I have to say the handling of this 'revelation' has damaged those attacking Ahern far more than him - and would imagine that it will give him (back) the sympathy vote and no doubt his ratings in the next set of polls will reflect this.
This coming from someone who believes he has lied/misled and has much to still answer for - just not this trivial accusation.
