I guess that is why reading a while before coming out swinging helps.
I consider the Cons to be the worst party.
I consider the Liberals marginally better but obstacles to any real progress.
I Consider the Greens to be largely AWOL on issues of social justice while no better than the NDP on the environment.
The BQ is not on the ballot where I live so it does not matter what I think of them.
I consider the NDP while imperfect to be the best. The best period.
Now that is out of the way.
Your comment about platforms does not make sense to me-- parties do more complete platforms in recent years than they used to and most of them follow most of the platforms they propose although the Liberals have been a little less faithful to theirs.
I don't just judge on platforms. We have House voting records, proposals each party has brought to the House and much more to judge them by.
It is a cop-out to say you can see no differences and have no preference.
