I think most of the resistance is knee jerk. Remember that Carole James claims to support MMP PR. You really support it, make it part of your platform.

 The cure for NDP twin personality disorder is to remove one of the personalities. People are much more likely to vote for you at all levels if you are consistant. If the provincials are saying "fuck the federal ideals, cos it does not suit us today"  it does not bring good optics. You understimate the power of idealism.  The poor voters, (the ones you depend on more than the other parties do) will just see you as just another shower of self serving bastards if you do not live up to your ideals.  And it takes very little to make a poor voter stay at home on election day.

 All sections of the NDP should support Pro Rep. Because it is fairer than first past the post. You have one side of the NDP being good and moral and another side trying to undo what the good ones are trying to build.

The federal NDP also needs to design a fair MMP system to put to the people federally (and provincially if they wish).  I know Wilf would be happy to help.  There are many MMP systems out there and it hinders their adoption because some are good and some bad . 

Currently the NDP can work at the attack ads on iggie. I am in favour. But thats half of it.  Making themselves more consistant and proclaiming themselves as the party for managing the government as opposed to the corporate raders of the other partys would pay dividends too.
