The problem with the Liberals right now is that I'm not convinced that there is anyone at the wheel. They've been spinning aimlessly for years. What they need is a leader, any leader, who can actually lead.
Agree, when you have NDP on the left/center spectrum and the Conservative on right/center spectrum - it doesn't give the Liberal a lot of ground to establish themselves as unique in the spectrum that separate them from the other parties.
Plus I don't think the Liberals really follow a solid ideology as this point, as they wandering back and forth from different spectrum without having a clear course of ideology as the CPC follows liberal/conservatism and NDP with social democracy.
What makes PPCA special is the issue of privacy/copyleft that makes them unique. As for transparency and open government, not so much as almost every single 19 political register party also advocate for open government and transparency.
