I will. I think it's a good place to do so.
The current game is in the U.S. political system. We have among the current presidential candidates no sincere champions of the deal post-January 2017. There is a narrow window between the election and January when the President of the United States could push for ratification in the Senate. That would be politically very ugly, but it is plausible.
It's another case for a charm offensive, because if the U.S. president is willing to take that risk before mid-January, then Canada should be there enthusiastically backing and cheering on.
