Not all indigenous peoples vote. A record number did vote in the last election, but you're still looking at less than half the population voting in federal or provincial elections, because they don't feel that federal or provincial governments represent them and their particular and unique interests.
Section 35 constitutional rights are unique to first nations, and we don't see a lot of federal and provincial governments championing that versus fighting that in court.
On the one hand, there's a lack of trust that you bring forward. Secondly, I've yet to see an MP go into any first nation, do a comprehensive presentation about what's in NAFTA, the current problems, what's being suggested, how negotiations are going, do economic cost-benefit analysis, and ask anybody what their opinion is.
