For some people it does not matter.
There are however MANY of us that look at this man, and see someone that has spent the majority of his life, living in other countries, coming into Canada, claiming to be the only political leader 'in touch' with the people that have lived here all of their lives.
Iggy knows that many of us believe his long absence from this country makes him totally un-suitable for any leadership position. (PM, Liberal leader, etc). Therefore, when on tour in Canada, he is trying to convince people like me, that while absent from Canada in body, his heart was here all the time. One of the things he has said to support this, is that he has never voted in any country but Canada, but that turns out to be a lie.
The issue of which countries he has voted in is/was minor, UNTIL HE lied about it, and did that lying in the context of a very important issue. That (willingness to lie) should concern everyone?
