The NDP,the Broadbent  Institute and various affiliated groups  came out  all over the press  before negotiations lauding their preferred choice and vilifying others such as ranked ballots as politicallyy driven as though their own preferred choice were not also the one that would benefit them them most.
 Then they struck a deal with the Conservatives that was not really a deal but a phony one. as the NDPy didn't want  a referendum and the Conservatives didnt want PR

Now their political shenanigans have backfired and they are furious. The only party that is happy is the Conservatives who wanted the FPTP all along...

 I think it is too bad they re not going with a ranked ballot  as that would make strategic voting unnecessary and would not necessarily be to the advantage of any party. The last election was different as the ai for many voters was to get rid of the  Harper Government.
